Whether or not quality of life increased during World War 2 largely depends on what you think is better. Being unemployed, or being forcibly enlisted to be shot at by Nazis.
It'd be interesting to do a life expectancy thing here... except.... life expectancy during the great depression INCREASED by 6 years.
Weird huh? Then it dropped during the New Deal until the recession of 1937. Decreased during WW2 of course.
Whether or not the economy improved, largely depends on what you consider the economy.
WW2 actually did fix the economy, but not in the way anybody argues it did.
WW2 actually caused shortages and austerity. People could not get the products they wanted, because the materials for them were vital for the war effort.
So they bought war bonds... and invested... and built up savings.
