It's "gentrification" when people with money move in, and "white flight" when they move out. Chase those tech workers out and watch public tax revenue, infrastructure, police force, and schools go down the tube.

Presumably, progressives want people making decent money to stay exactly where they are and neither come nor leave

But the real reason for the protests is that it offers a sense of belonging and meaning in a post-religious world. God may be dead, but now we have social justice

Stay safe out there guys. Lefties can be dangerous[1]
