I see your point, but I look at the houses going up all around me and their prices, and I wonder where folks are getting this money from. I know what I do for a living and how well it pays, but people who make less than half of my salary are buying homes that are twice as expensive. Also, talking to realtors they mention that homes are sometimes sold before they hit sites like Zillow and such. Sight-unseen, waived inspections, $20K over asking. This can't be sustainable.
It’s more than just salary. Take an elder millennial who has been working in bigtechco for 10 years or so. The RSUs they collected in their early years could be worth >10x today. Same with crypto over an even shorter term.
