Question

In what ways did world war 2 most directly affect consumers at home

Answer 1

Surprisingly, in many ways. However it mostly depends on which country.
I'll give you an overall answer that all countries had in common.
For the most part, there was food regulations and a lot of "support your military" propaganda. 
Food was scarce, and the military needed donations. 
This also goes as far as bedding, vehicles, and communication devises. 

I hope this helps! :)
