I live in the Bay Area now, but I grew up in Hamilton, New Zealand. I'm back home with greencard stuff at the moment.

On my parents relatively modest street houses are now selling for $850k. These were houses that cost $400-500k ten years ago. People simply do not make the incomes necessary to make these prices sustainable. I have one friend, of everyone I grew up with and went to University who's making north of $100k as someone in their mid-late twenties. Everyone else is making substantially less. Whereas in the Bay Area half of my friends are making $100k + (and often substantially more than that).
