What was true of the U. S. economy after World War 2

It grew bigger and stronger.

Explanation:

After the war there were many workers that had been making military equipment and vehicles for the armed forces for years and when the war was over the factory workers all over America now made and produced more goods for common life post WWII such as cars, tvs, refrigerators, houses, etc. There was more of a demand of products of that nature which then brought on more workers to build them which made companies bigger from increased revenue and increased revenue for the steel and lumber companies, which made shares of those companies stocks more valuable in the economy. After the war there was also research to be conducted when the Allies now had access to German inventions such as jet aircraft and recoil operated muzzle boosters to make guns fire faster. More and more jobs were being created and more and more money was made for everyone all over America. In a way, WWII saved the U. S. from more devastating years of the great depression.
