I do not think FDR was as great as people say. Seems that FDR's policies actually prolonged and exacerbated the economic disaster, swelled the federal goverment and prevented the country from turning around quickly. WW-II is what ended the so called "Great Depression", The "New Deal" hampered recovery. FDR just happened to be President as things fell into place.
I would say that the New Deal and WWII helped to create jobs. The problem though is to ensure that the jobs created are an investment that will help to fight inflation after the recession, otherwise the recession will be replaced with inflation.
If I were the all-powerful King of the US at the time of the depresion, here's what I'd likely have done:
1. Not take action until we hit deflation.
2. As soon as deflation begins, start lowering interest rates to counter it, and keep doing so until we reach 0% Federal reserve rate. Since ther was no minimum wage at the time if I remember correctly, salaries could have adjusted as needed.
3. Once those two conditions were met, then, and only then, print just enough money to counter the deflation, and spend it on the following, prioritizing according to circumstances:
a. paying off the federal debt if there was one at the time.
b. give school vouchers to the unemployed so that they could learn a trade or profession.
c. invest in a blobal ethical stock fund.
The act of printing money and putting it into the economy would have helped counter the deflation. The low interest rate woud have given the government some wiggle room in case it should print too much money, so as to raise interest rates as needed to fight inflation. And after the depression:
The lower federal debt (assuming there was one previously) would have made it easier for the government to reduce its fiscal output to below its revenue as a way to take the money back out of the economy again. The newly trained workforce would return to the workforce more productive than before, thus increasing the economic value of tis output, which would also have hedged against the risk of inflation and high interest rates. And any investments acquired by the feds during the depression could then have been sold after the depression as a means of taking that money back out of the economy again.
This woudl have been a perfect scenario, allowing the government to put money into the economy during the depression to counter deflation while at the same time placing itself in a position to counter inflation after the recession, which would have shown forward planning.
Now, tobe fair of course, that would be an ideal scenario. Unfortunately, WWII cama long, and certainly sometimes there are more important issues to deal with than the economy.WWIi created jobs which was good to get the economyout of recession. But since money spent on war is not really an economic investment, inflation or high interest rates following the recession was inevitable.
As to what we could have learnt for this recession, I would say that while it's understandable that the government needs to put money into the economy in times of deflation, it needs to do so in such a way as to place itself in an ideal position to fight inflation after the recession, as inflation is often what follows a recession. In this recession, there was no forward planning. Sure the stimulous packages created some jobs, but how will we then counter the upcoming inflation? We'll have a higher debt, making it harder for government to then keep revenues so as to keep them out of circulation. Money put into the auto sector provided no skills upgrading for workers and just propped up industries that had already proven untenable on their own, so in times of inflation, these workers will produce nothing more than before, but with more money into the economy, so inflation and high interest rates become a real threat now, with governments ill -prepared to deal with it when it comes.
