The development of a country, or even a city, is inseparable from a large number of laborers. And the most basic need for the development of a city is construction workers. Only when the construction workers build the factory can the factory be started. Roads and other public facilities have been repaired to allow the product to circulate.

However, construction workers are also very hard, exposed to the wind and sun all day long, and there are certain construction risks. Even in the 21st century, construction workers are still exposed to the wind and sun, and there are certain safety risks. Therefore, in later generations, construction workers, sewer cleaners (that is, dung diggers), stevedores and unloaders in big cities in China ...... The dirtiest and most tiring work is often done by migrant workers. And those migrant workers who are willing to do the dirtiest and most tiring work are generally from rural areas, so they are also called migrant workers.

This is not only the case in China, but also in Europe in the 21st century, there are also a large number of migrant workers. Why do several developed countries in Europe accept a large number of Middle Eastern refugees? Do you really think they're kind? In fact, it is because developed countries such as Britain, France and Germany have a large number of the dirtiest and most tiring jobs in China, and their own residents are unwilling to do them, so they can only count on refugees and immigrants. After all, people have good welfare for their own citizens, and they don't have money to do dirty and tiring work. Only refugees from outside, because they do not have a local hukou, cannot find a proper job, so they can only go to the construction site to do the dirtiest and most tiring work. Moreover, they do not dare to strike at every turn like the local workers. Because, if you dare to blow up the thorn, you will be sent back at any time......

As for Huaxia, there are no refugees. Because, in the vast rural areas, some are migrant workers. Even, much more than European refugees came. Therefore, Huaxia's infrastructure has always been very strong, because Huaxia has the largest group of migrant workers in the world. Before Marin crossed, it seemed that the number of migrant workers in China was close to 300 million, which was about to catch up with the population of the United States, more than the total population of Britain, France, Germany and Italy.

You must know that Britain, France, Germany and Italy are the four major powers in Europe. As a result, the combined population of these four countries is not as large as the number of Chinese migrant workers. Then, it is not surprising that infrastructure and manufacturing cannot compete with China. In the 20th century, with the leading level of science and technology, these four countries can still compare. When Huaxia Technology gradually catches up, the four countries will not be able to compare.

In fact, Matthew made it very clear in his writings that the reason why England was the first to carry out the industrial revolution was that in addition to the development of steam engine technology, the "enclosure movement" produced a large number of landless peasants, which was also a very important prerequisite. If you don't have enough labor, even if you have machines, it's useless.

As far as Beihai is concerned, it is still in the primitive accumulation period of "land reclamation and farming", and it is an agricultural country. However, if we want to go further and evolve into an industrial country, we must have a large surplus labor force, that is, we must have enough migrant workers. Otherwise, how can industry be developed if there is no one to be a worker?

The society has developed to a certain extent, and the division of labor has become more and more detailed. Although the propaganda says that there is no distinction between high and low work, some dirty and tiring work is still not decent enough to say. In later generations, even if moving bricks earns more than some office workers, the "grade" of the two is different. When parents are scaring their children, they will only say "if you don't study hard, you will go to the construction site to move bricks", but they will not say that if you don't study hard, you will become a little white-collar worker......

All in all, the work done by migrant workers, although they are not less, is a kind of hard work that is not respected. The so-called "work does not distinguish between high and low" is just a lie that fools people. Otherwise, why would the official ape exam break the head? You must know that migrant workers earn much more than ordinary official apes.

Of course, although migrant workers have a low social status and do the dirtiest, most tiring and hardest work, they are also very important.

In later generations, migrant workers were mainly engaged in construction, transportation, agricultural trade, services, and industry. And these industries are all very important industries.

Needless to say, buildings are needed to build houses and roads, and the importance of transportation is also extremely important. Without manpower to transport supplies, commerce would not be able to circulate in a timely manner. Or, the cost of transportation is too high, which will affect the development of business. Needless to say, there are no migrant workers in the suburbs of the city to build vegetable greenhouses and pull them to the vegetable market to sell, the source of food for urban residents will become a big problem.

Needless to say, the service industry, express delivery and food delivery, both require a large amount of labor, which can greatly facilitate people's lives. In the industrial field, migrant workers may not have the best skills, but they are the cheapest labor. Moreover, they are more obedient and honest than urban workers and will not "rebel" casually.

These are all modern migrant workers, and in this era, migrant workers are also very important and in great demand. For example, the Goslar silver mine in Marin requires tens of thousands of laborers, the kind that mines full-time. Similarly, coal in the Ruhr area requires a large number of coal workers to excavate. After all, there was no mining machinery in this era, and it was only necessary to rely on manual excavation and transportation.

Because of the demand for coal in industries such as honeycomb coal and steel, Marin estimates that at least 50,000 or 60,000 coal workers will be needed in the Ruhr area. At present, there are more than 30,000 coal workers in the Ruhr area, and there is a large labor shortage.

If it had been left behind, it would have been recruited directly from the populated manors. However, at present, in the Beihai Kingdom, every labor force has been used to farm, and there is no surplus labor force to be found. Therefore, if you want more coal diggers, you can only recruit them outside the North Sea Country.

But the problem is that the other German states began to guard against the North Sea State, and did not let their young men go to the North Sea State. Therefore, Marin has deeply felt the shortage of labor in recent years. Not to mention the digging of silver mines and coal mines, even farming, there is a shortage of manpower.

In addition to the mines, which require a large number of laborers, other industries also need a lot of migrant workers. For example, in the seafaring industry, thousands of migrant sailors were recruited from all over Germany in Bremen alone, making a great contribution to Bremen's seafaring trade. Of course, the current Bremen is Marin's territory.

In addition to miners and shipwrights, a large number of migrant workers are also needed in the transportation industry in this era. After all, there were no modern means of transport in those years, and transportation was extremely difficult. If it is a long-distance transportation, it is enough to use a merchant ship or horse-drawn carriage. However, for short- and medium-distance transportation, it seems that using a trolley is more efficient and cost-effective. However, for every cart used, it required a strong man of life...... In addition, it takes a lot of migrant workers to press the coal into honeycomb coal and transport it to various places......

It can be said that because of the lack of migrant workers, many industries in Beihai have difficulty developing. Previously, Marin specially sent people to recruit a large number of laborers to mine and serve as sailors in the North Sea Country. However, it is quite difficult to do. Because, Ma Lin didn't think about recruiting migrant workers before, but directly asked his family to move to Beihai Kingdom. However, this kind of immigration was resisted by the vassal states, and they had to find another way. Then, recruiting migrant workers becomes the best option.

Migrant workers are not immigrants and cannot be used as a measure of national strength. You must know that in this era, the population is also an important indicator of the strength of the country. If Marin wants to immigrate 10,000 strong men, including the families of these strong men, there are tens of thousands of people, which is very eye-catching. And the arrival of these tens of thousands of people will also mean a great increase in the strength of the Beihai Kingdom.

But if it is replaced by migrant workers, it will be much more inconspicuous......

Because, migrant workers all go to work in a certain place alone, without their families, and their natural goals are much smaller. Moreover, migrant workers are not immigrants and do not change their household registration. According to official data, they are still citizens of their original country, and they are still taxpayers of their original country. Unlike direct immigration, not only is the target big, but it is also tantamount to openly digging into the corners of other people's walls and robbing taxpayers, which is naturally disgusting. But if you switch to recruiting migrant workers, the likelihood of boycott is greatly reduced. After all, you're just offering jobs, not digging into people's corners.

Ma Lin calculated that if the miners, construction workers, transportation workers, shipwrights and sailors of the Beihai Kingdom were replaced by foreign migrant workers, more than 100,000 young and strong laborers could be replaced from these positions. These young and strong laborers, whether they go to farm or serve as soldiers, will bring great benefits to the Beihai Kingdom and Marin. Moreover, it can also generate a large amount of GDP......

In short, if a large number of cheap foreign workers can be introduced, it will bring huge benefits to the economy of the North Sea Kingdom, and it can also help Marin make a lot of money. After all, many industries in Beihai Country are owned by Marin. Migrant workers come to work in Beihai Kingdom, to a large extent, to create wealth for Marin. If hundreds of thousands of migrant workers can be recruited, then the economy of Beihai will probably "take off......
