> Have you never been to London? There are homeless literally everywhere

I live in London currently. There are almost no homeless people. What are you talking about? It's one of the largest city I've been to where I've seen the least amount of poverty.

I'll also say that London is super safe, you'll almost never see crazy people in the streets or public transport. I regularly take the bus or the subway at late hours and I've never seen anyone dangerous or looking for trouble.

You definitely picked the wrong city.
