Li Yuan spent 15 invention points to exchange for two books, because there was an option to spend a little invention value in the mall to get a physical book, and he did not hesitate to click it.

Although the knowledge in the books will be etched in his mind, this mode of swallowing dates is suitable for simple things like origami, but it is not convenient for those who need to study how to work for cash.

Among the backpack options he has five packs of "fresh air from the Hereafter" and a few miscellaneous items.

After spending nearly fifty invention values for the lottery, Li Yuan was not so unlucky, and he also drew more practical small things, such as five-mao lipstick to prevent dry lips, a pack of Lay's potato chips, and a small bottle of toothpaste.

It's just that the egg hurts and he didn't brush the toothbrush, and brushing his teeth with green salt mixed with wicker branches in the past few days has made him physically and mentally tortured.

As was customary, the two books in his backpack appeared from his sleeve robe, otherwise it would have been difficult to tell if he had created something out of thin air.

It's also important to mention that items taken out of the backpack cannot be put back.

Li Yuan carefully took out two books from his cuffs, "On the Economic Crisis of 1935~1942 in the United States" and "The Golden Plum".

The first book is very thin, only about a centimeter thick, and the cover is also very beautiful, a silhouette of Roosevelt. The second book of the golden bottle of plum is very thick, because there are many exquisite illustrations in it, he is red and red-eared when he sees it, and he can't stop it, Li Yuan closes it at a glance, and puts the golden bottle plum under the first book.

Then he reopened "On the 1935~1942 American Economic Crisis", the words are simplified, but it effectively prevents the prying eyes of others.

With the gradual interpretation, Li Yuan gradually understood the historical economic reforms of the United States during this time period.

In fact, the economic crisis in the United States began to break out as early as 1929, and 1935~1945 was the time for Roosevelt's New Deal to carry out economic reforms.

In the summer of 1929, U.S. stocks rose wildly, causing Americans to talk about stocks when they met, but this false economy, like the economic bubble in Japan in the nineties, burst at the slightest touch.

On October 24, 1929, the U.S. financial community collapsed, and stocks fell into the abyss from the peak of more than $500 billion overnight, making more than $500 billion in assets disappear overnight, and the price fell so fast that even the automatic display of stock market could not keep up, and the collapse of the stock market led to the Great Depression that lasted for four years.

Since then, the U.S. economy has fallen into the quagmire of economic crisis, and the bleak scene of the once thriving American society has gradually been replaced by a bleak scene of stockpiles, unemployed workers, and closed stores. Businesses went bankrupt, banks collapsed, and the country's financial community was suffocated. The value of agricultural products has been reduced to the lowest point, and it is not uncommon for operators to pour milk into the sea and burn grain and cotton in public.

The number of unemployed people in the United States has risen from 2.7 million to more than 10 million, which is an extremely frightening number, accounting for almost one-tenth of the population of the United States.

At that time, the president of the United States, Herbert Hoover, came to power and shouted slogans such as "one chicken in every pot" and "two cars in the garage". Later, due to miscommand, the US economy deteriorated.

After Roosevelt came to power, he adjusted a series of economic policies and began to use the state to intervene in economic development.

State intervention in economic development, which was a means of a planned economy, and in the United States, a highly developed capitalist world, it was absolutely insane to adopt the communist economic mode of Soviet Russia at that time!

But the effect was also obvious, Roosevelt's New Deal was a success!

In fact, there is a great man in China who did the same thing in the South China Sea...

It is ridiculous to have a communist economy in the capitalist world and a capitalist economy in the communist world, but they have succeeded.

A few hours later, the sky was getting dark, and several palace maids stood respectfully behind Li Yuan with palace lanterns, and at some point, he also wore fur coats on his shoulders.

Although the lights are not as bright as in the daytime, reading a book is enough.

On the stone table, squatting on the small earthen embryo stove, boiling ginger soup on a scorching fire.

After a long time, Li Yuan closed the book, exhaled a deep breath, and asked, "Where is Jue'er?" ”

The painting screen poured a cup of ginger soup for Li Yuan, and said softly: "Sister Jue is still young, and she is playing happily today, and the concubine saw that His Majesty was fascinated by reading and reading, so she let her go back to the palace to sleep first." ”

Li Yuan nodded, drank a low cup of ginger soup, the hot ginger soup drove away the cold, the stiff limbs gradually warmed up, and the stomach was also burning like a stove, which was very pleasant.

It is no longer absurd to implement Roosevelt's New Deal in Datang to solve the problem of homelessness, it is simply a fantasy, but it is enough to absorb some essence.

The most important measures of Roosevelt's New Deal were: first, to rectify the banks, abandon the gold standard, and stimulate the depreciation of the dollar to benefit exports; Second, the government regulates the production indicators of factories and controls them to avoid waste of resources; Third, the state builds a large number of public facilities and hires workers to solve the employment problem; Fourth, improve social security benefits.

The people in the northern part of Guanzhong became displaced because the Turks went south to plunder.

In ancient China, the most common way to deal with such problems was to dismiss the displaced people, send them back to their homes, and then have the local county order to provide them with food relief.

However...

This is just a means to prevent the homeless people from gathering and rebelling, the food distributed is not edible to the local people, and it is even more common for poor families to sell their children and daughters, and if they encounter landlords, there is no surplus food in their homes... Then you can only starve to death!

Li Yuan had already thought of a way to rescue the homeless, but how to get Li Shimin to adopt it?

"Come on, get up and go to Zichen Palace!" Li Yuan's eyes burned, and he got up and shouted in a low voice.

As soon as the words fell, the eunuchs and maids of Da'an Palace became busy.

The two palace maids on the left and right opened the way with lanterns, and the bright lights were like long dragons, followed by eunuchs carrying soft comparisons on the winding corridor.

The Zichen Hall in the court is the residence of successive queens.

There was already a eunuch riding a fast horse to go to the eldest grandson Wuji, otherwise wouldn't it be rude to let the father-in-law wait for his daughter-in-law?

If it happens that Empress Changsun is resting, do you want Emperor Taishang to come for a trip.

When Li Yuansheng arrived, the eldest grandson Wujian put on a phoenix robe early and waited outside the palace.

"Daughter-in-law see father-in-law." The eldest grandson Wujian looked haggard, and his fair face was tired, but there was a joy that could not be suppressed.

Without waiting for Li Yuan to get off the soft sedan chair, she continued: "Jieli Khan is menacing, but it can't stop the heroism of the people, and the daughter-in-law remembers that the Jieli Khan of the year forced the father-in-law to hang his hands and feet, and he was angry, and the people of the world can be regarded as revenge this time." ”

"The people of the world do have a hand in leading the army." Li Yuan praised Li Shimin painlessly, ancient and modern emperors, among the kings who know the art of war, Li Shimin must at least rank first.

The eldest grandson's innocent little cleverness Li Yuan also knew it, and used Li Shimin's record to warn him a little, if he was replaced by those mediocre women, he would speak differently. secretly praised Li Shimin like this, alerted Li Yuan, and eased the contradictions between the two by the way, even Li Yuan himself couldn't help but admire the art of speaking even more in his heart.
