The 20s began after World War 1 and many US citizens believed that it was Wilson's progressive and liberal politics that made them join such a gruesome war that they didn't even have to participate in. They wanted to become more conservative and republicans easily won, however, the great depression came and since Hoover couldn't solve it, and he was a millionaire and wasn't very popular, people turned to those who could solve it. Since it was FDR who could do it, it was thanks to the events in the 20s and 30s that many of the policies that made America great after World War 2 were introduced.

In the postwar years of the Cold War, the technology made a real boom in the agricultural sector. The new machinery, the creation of better chemicals for treating the soil and plants, as well as for their protection from pest, resulted in much increased agricultural production.
The arable land that a single family was able to work on with the new technological advancements increased significantly. That led to significantly increased production, and also a significant increase of profit for the people engaged into agriculture. The higher production led to more stable food sources, thus in numerous countries the malnutrition was wiped away or minimized.
