I don't know that at all. People in public housing that I know and see are not especially from South America.
> people removed from homes for domestic violence by court (divorce)
This is classic why the husband moves out, have you ever dealt with family courts as a male in Poland, nothing rings the bell for you? So a male homeless must be violent alcoholic, right? I'm happy that your life and family are doing okay. Once your life will turn more difficult, Polish society will dismiss you as a violent alcoholic and no help or support will be awaiting. Will reveal you one more secret, Polish male homeless are in Germany and Netherlands. Occasionally you hear about them in media when someone beats them to death or sets them on fire.
They'd happily sell but for 1mln PLN.
> people looking for something better they already have, preferably free money
They'd rent but they are also aggressively sly, dismissing every perfect tenant. In the end they indeed end up renting to another non-paying sly who will tell them exactly what they want to hear.
At this point of the real estate the market, it's the owners who want free money.
