Tbf it might make more sense but considering people in that situation in America will be suffering already, their thinking might be a little impaired by the stress of trying to survive. Also just uprooting your life and moving away from where you live is no easy thing, especially if you're moving from your needed support network who and essentially going to somewhere new where you don't know anyone and so are isolated whilst still being vulnerable, because a new city racks up the hours and costs quite quickly. There's also an element of risk in moving somewhere new, and if everything goes pear-shaped then you could find yourself at square one and even worse off then before.
