Step 1 to fix out of control real estate prices and suburbia depression is not public transit.
Step 1 is to deprioritize cars. No more free parking, no single family home zoning, free-for-all zoning around train stations and bus stops.
Step 2 is to keep deprioritizing cars. Ban highway expansion beyond 2 lanes in both directions. Match demand and supply with tolls. Excess revenue goes towards funding public transit.
Step 3 is to fund public transit. Private sector will see massive opportunity to build out private bus lines and trains (see Brightline in Florida). The real play is not ticket revenue, but real estate appreciation around public transit. Republicans should get around this idea with private equity guys. This is a no brainer to me.
In conclusion, the key to this morass to make car owners suffer and switch to real estate appreciation to incentivize private development of transit systems.
