I find this picture interesting because of the sign in the window. The implication is that you have a duty to buy things in order to make work, and create jobs. I think we still hear this sentiment today, that we need to start spending in order to make things better. I feel we are in the mess we are in today because we have borrowed too much, spent too much, and spent it on a bunch of silly unneeded stuff.
My shop sign would say: "Spend Less, Save and Invest More, Stop Buying Silly Stuff, and Give Generously to make our Nation Stronger". I don't expect many to sign on.
