Great deprresion in lifes

What i see in this picture is a sign.That sign says that "Jobless men keep going. We can't take care of our own. " I guess what they are trying to say is that. during the great depression they couldn't take care of their workers.So, maybe then men would leave states to go look for a job.And that sign they have in the background is what put so, when someone asks why are they leaving, they would look up at the sign and that would answer their question. The difficulties they had was men leaving states to go look for jobs. So it affected the population, and the economy.
