coffee sugar and gasoline were been shortages in the second world war.
America instituted many price and wage controls during World War II to hold down inflation. Rent control got its start during the war and employers starting offering benefits such as health insurance to bypass wage controls. Shortages did occur and life was quite tough for those back home during the war. Once the wage controls were released after the war, prices did increase significantly. Prices went up 37 percent from 1944 and 1948, about the equivalent of the increase from 1976 to 1980.
Childhood was likely difficult in most parts of the world during World War 1. There were food shortages, and many males were absent from the home and serving the war.
It was hard in WW2, with rationing and shortages of necessities, so mostly people had to make do and mend, re-use or just be out of supplies.
