Growing up in Berlin I was always depressed because of stupid/dumb people who lived around me.
I wanted to move into a neighborhood where only smart people lived.
This dream came true when I moved to SF. Here prices are so high only most smart people can afford to work and live here.
You don't understand value of this kind of economic segregation untill you spend a few week in poor income localities.
People have different beliefs, it's hard to make people act in a same way.
But we've found that money is one such thing where most people agree if not all. So why is it bad that people who collectively value money are able to afford SF and those who don't can't afford.
We find security among a group which values same thing as us. And most people in SF value meeting economic demand, making money and lots of money.
