Europe

Maybe you are taking tent “city” too literally, it’s not so much a city as sometimes a small encampment but they exist.

Not really. In western europe they have emergency housing available for free to homeless people. The document you linked will agree with that. In most western european countries you can use those resources as long as you need to, and get a social worker so you can work towards social housing.

Again, you wont find homeless in our cities. There are beggars but those arent homeless. You should visit sometime if you dont believe me. Most americans are surprised to see the lack of homeless people in western european countries.

Living in western europe isnt expensive, with around 3K in income you can live comfortably and enjoy all luxuries. Food is generally cheap, same for utilities. Taxes are heavy on upper middle class.

There are a lot of expats that do IT and live very comfortable with a normal wage.

I personally spend around 600 Euro on my mortgage and around 300 total on utilities + health insurance.

If I can give a couple good spots of how good life can be I recommend visiting luxembourg, belgium or the netherlands.
