Did you build Austin? What constitutes a "local"? No one anywhere in America (or anywhere on Earth that I'm aware of) is required to pay a "foreigner tax" for moving into another city within the same country, which they are already a citizen of. Everything is supply and demand, everything is a push and pull. If Austin is bursting at the seams, it will take a few years for investment and policies to relax it. If Austin starts to empty out, slowly the city will shrink. The ebbs and flows of change are always happening, nothing is constant, everything is in motion. Austin is better served by attracting people than it is by pushing people away.
