I heard this guy talk at this year's Launch.co conference. It's great that people are actively trying to solve California's famous issues, but it's hard not to see the Six California plan as socio-economic gerrymandering. The wealthy Bay Area essentially gets to wash its hands of the less wealthy interior cities. I think there's a better way.
I'm conflicted about this. I strongly believe in focused local government, and California is awfully big. At the same time, I'm with you on socio-economic gerrymandering. This would be awful for much of the state.
