I don't think you really realize what is "poor". Everything but the car is pretty cheap, and only the cell phone with a $30-40/month plan is necessary for modern life.
People working a couple jobs 60+hrs a week to spend half their gross income on a bad apartment, and buy overpriced junk food at the local supermarket, and don't have a reliable car or time, to go to the cheaper grocery store in town, aren't really having a "good time".
1/3 of the US households have less than $50k per income... So after taxes, rent, utility bills, health insurance? They get down to $3-400 per week for food, transportation, clothes... They aren't ordering $150/month tv/internet packages to watch the disney channel on their 87" TV, or getting 4-5% cash back credit cards.
We make a decent amount of money, but even I have a hard time forking over what a semi-reliable car costs these days, and that's with having the space and tools to do most of the maintenance and simple fixes.... And we have no mortgage or car payments.
