Plenty of people. Entire generations were raised and indoctrinated on concepts like "You'll be homeless if you don't get a degree" and "You should invest and let your money work for you".

Then factor in pensions and retirement investments. ALL of this matters. This mind-blowing realization that it was all bullshit came well after we invested, got that degree, etc,. Those who can't see it are either from the generation who preached it or those fortunate enough to have dodged it themselves.
