I can only assume you haven't spent a lot of time in the EU... Switzerland (which is not in the EU) is the only European country I've been to that does not have a very visible population of homeless people.
It's not a small, nuanced difference but literally night and day. Have you really seen tents downtown in any city in Europe?
I'm American but most Europeans I know struggle with living in the Bay Area because it's such a shock for them.
You're saying it's worse in SF/Berkeley, and no doubt it is. But it's not "solved" in the EU.
I've spent 20 years living in various countries in Europe. I stand by my statement.
There's a homeless problem in other cities, but we don't have tents downtown.
The link below lists around 30 US cities with tent cities downtown.
Edit: autocorrect -.-
- The EU
- San Francisco or Oakland
