I have neighbors who bought their $3m homes when they weren't even $800k (adjusted for inflation). And since salaries + stocks have grown much faster than their property tax burden (basically frozen) - they're all retiring early.
People have expectations based on what they grew up with or what their parents grew up with or what they saw people achieving as they grew up. Can't blame them when they get out into the market and finally start saving that they're gonna be 10 years behind for the rest of their life...
