Well around here we do get illegal immigrants, but they don't usually come in entire families - logistics are tougher. So the whole shacking-up-with-30-people-in-a-normal-house-cause-it's-cheap thing only partially applies. People who are dirt poor like that still shack up in small lodgings to share rent as much as possible, but as you can imagine them not being family makes them less eager to share EVERYTHING.
But anyway, didn't know it was that weird down in the States.
Next thing you know you're living in a gated community...which would be pretty awesome because you could watch the lowlives outside from over your wall. But I digress.
My new place is in a former port/stevedores district that has been turned into a condo paradise for developers and yuppies, which gives it a weird vibe. During weekdays, the stevedores are ubiquitous and rule the place, but in the evenings and in the weekends all you see is rich(er) young people, as well as some old inhabitants who owned their house before the price boom. The only place that stays 'folksy' during the evenings and weekends is the stevedore dive two stories down from my flat. Gotta love the nightly brawls and song.
