I think the people buying these things are contributing less to retirement than people think.
Also, there's a lot more $200k+ paid people out there than people think. Basically all the "you're part of the problem" careers will get you there if you grind long enough. Cop who's abusing the O/T system, doctor, lawyer, enterprise sales guy, professional engineer, etc. Add a $100k+ woman to the household and it works out. It doesn't work out great but it's very doable.
If the IBB dentist isn't making $200k he could be if he had less morals.
