And those institutional ads, run to keep brand names in the public eye, always had the message to buy war bonds to save for the day when you would be able to buy the appliance, kitchen, washer, house, car etc. that you could not buy now. That pent up demand for consumer goods from the decade of the Depression and then the half decade of the war and then the Korean War helped to fuel the economic boom of the 50s and early 60s. I was surprised to find, when I read shelter magazines of the early 50s, about the shortages of home heating oil and natural gas because of the Korean War effort and the insulating and heat saving tips they offered. It was similar to what they were offering in the 70s.
Sadly, you are right that it was basically the tooling up for war that finally brought our economy out of the Depression, but at a horrific cost. Every time there were signs of improvement before, the Republicans in Congress would cut back the aid to recovery too soon and the economy dipped again.
