The population of Detroit declined from >1M in 1995 to 630k today.

That would not be the case if they "moved into welfare" or became homeless.

You seem to have the idea that welfare systems in US cities can handle 40% of the city becoming jobless. I assure you this is not the case.

Unless you're trying to convince me that several hundred thousand people just died, they very obviously moved out.

I can't prove that Detroiters specifically all found better paying jobs, but there is ample evidence online that shows that the real factor crushing the middle class is the sheer number of Americans being catapulted upwards.
