Try wealth inequality. The rich get richer, the poor get poorer, at some point poor becomes homeless.

You’re importing millions which puts pressure on housing and employment where they compete against locals depressing wages. Additionally many from Eastern Europe, Middle East, Central Asia and Africa are semi skilled and unskilled who in turn either can’t land a job or don’t earn enough.

Exactly! In Europe, people that are leaving in the streets are mostly illegal immigrants, drug addicted or people that refuse helps for mental issues or culture (gipsies).

That’s guaranteed not to be true but you are free to believe that if it makes you feel better.
