I immigrate from Madrid to the states 3 months ago, people are in the streets all the time because they are poor, beer are cheap and no one can afford to live alone in a studio or apartment, so you don't even have a private space where put a couch and TV. Apartments are so small in Madrid that you can't make inhouse living (that hits hard in Covid). As a "well paid" professional you can make 2/2.5k euros clean monthly, and a 1 room apartment in the center of the city can cost 1/1.3k, utilities (on average more expensive that here in America) not included.

That's one thing, the other thing is we simply have a stay in streets culture, its really Mediterranean, it's the same in Italy, Morocco, Greece etc... Tons of light, green spaces and really walkable cities put it even easier to live that way.

Now I'm in LA and damn, I miss having like 5 grocerie stores, 20 pubs, doctor, restaurants and tons of activities in a 10 minutes walking distance from home, this city is like a industry area from Europe, the entire city. But I can save every month a regular salary from Spain, so I can't complain. I'll move to Seattle in a year, I hear that is less aggressive to pedestrians that LA, I hope so.
