I can't even touch the housing market in an area inconvenient to my work without literally hundreds of thousands of dollars in liquidity. That is cash that I simply do not have, nor do I have wealthy relatives that can front me the money. Please don't assume that just because an engineer has, what looks like a high income on paper, that they can even afford houses that cost millions of dollars in a high cost of living region as the Bay Area.
My coworkers that have set down roots here have to drive hours, and they're also making "at least 100k a year". What about the engineers that need jobs and homes, and the people that move just for their job? City's full, go away.
