@freemo Not sure about the specific situation in the US, with less social security.
I have a suspicion that descent into homelessness here is mainly some "can't deal with the bullshit" stuff. Like the gouvernment agency responsible for paying out the pittance someone is supposed to live on asks for the same info for the thousandth time and some people just give up.
Might be that men are more susceptible to such... but unsure if there would be any way to not become homeless in the US if no job comes along.
