Add in $700/month in food, $300/month in insurance premiums, $1,000/month for a car (between car payments, gas, insurance, average of 10 parking tickets per year and $200/month for a garage parking spot). All of a sudden you're living paycheck to paycheck.

And in the end they're still renting, and not able build wealth of their own.
