I see what you're saying... but I'm young enough that I could loose my house and cars and 401k and all the other junk, and still make it back in 20 years, probably less because I'm more productive. Granted, that's not true for everybody. But i think it's only true for the super rich, and the very old. My dad's doing pretty well. if he had to start over... I don't know if he has enough time to make it
all back but he's smart and hardworking. I'm sure he could make a dent.
I think a better argument would be, "you have to start over" and starting over sucks.
