The U.S. was economically recovering from World War 2, the Great Depression, and other things. Most working class Americans had a hard time affording food because of that. So, it was not like they could easily get away from being skinny, anorexic, etc. during that time. They were too busy saving or investing money for their bills, children's futures, and careers to improve the U.S. economically before younger generations got spoiled rotten by America's improved economy. Now, the younger generations of America today are barely affording food because of increasing wealth inequality, increasing cost of living, and decaying infrastructure decades ago. So, working class Americans are economically screwed again, but it is to benefit antisocially greedy oligarchs only. So, you better expect skinny people, anorexic people, and starving people to become a bigger population in the U.S. The ruling class in America are kind of doing what Nazis did to Jews in concentration camps by starving them to death. Except America is the concentration camp for working class slaves with the illusion of freedom disguised as the democratic party, republican party, human rights, etc. Overall, the ruling class has exclusively cut-throat power that lets rich men live in luxury during this pandemic while working class Americans suffer more with each new year rather than suffering less with each new year.
