Not sticking up for the man, as his own Karma has led him here for sure, but there are PLENTY of people who've intelligently built their wealth while living in such places. It's a much better option than an apartment rental, and it provides a perfectly comfortable environment to thrive.
And as for those owning "normal", median-level or better homes (**NOT** including parents' houses

), I'd be surprised if 20% of getbiggers meet the definition. Really.
