I said nothing about "choosing to cheat society". Perhaps check your own biases? I also didn't say anything about "offering services".
From the charts in your article it still doesn't seem unlikely that many homeless people migrated there for the jobs, a ka money - 30% in the "1 to 4 years" bracket, 48% if you go to "up to 9 years".
In my city (Berlin) it certainly seems to be the case that it is often immigrants who end up homeless, presumably because the social net for citizens doesn't fully apply to them.
this myth gets repeated and has no basis in reality. people in every city that offer any kind of service for the poor think that this attracts poor people. i guess it’s easier to believe that people are choosing to cheat society than society failed to provide for them
