What is her salary? What is she paying in student loans? Medical payments? What is her job at Facebook? What is the non-profit she's running?
Lousy reporting!
Anyhow, she's not starving, that's for sure.
Regarding medical payments: these are even easier to defer than student loans. I am highly skeptical the reason this woman lives in her car is because she is scrupulous about paying off her medical bills.
Food: I am a stress eater, so I understand why she is fat. However, the argument — I am addressing what liberals inevitably argue — that the only reason this woman is fat is that she can afford to buy only junk food is nonsense. Life is hard; people eat. Again, I understand this. But “junk food” is not free, or necessarily even cheap, especially if there is no way you can boil the pasta yourself (because you're living in your car). Have you been to McDonald's lately? Buying only 850 calories can cost more than $12, and in Silicon Valley, it probably costs more than that. To eat what this woman has to consume to maintain that weight, you'd have to spend a great deal of money on food.
You don't necessarily have to live alone. If you post an ad on Craig's list that you have steady employment at a place such as Facebook and would like to rent a room in someone’s place for, say, a year, you will get responses. If you pass a simple internet-based background check, and you can pay a few hundred dollars in cash a month, you'll get a room in someone’s house.
Another thing, this woman was willing to go to the press...why didn't she go to Facebook’s HR department first? The last thing FB as a corporation wanted was an employee -- especially a black woman in lily white Silicon Valley -- giving interviews, telling the world she is forced to live in her car. I'll bet she could have got all the above advice from them, plus some help finding a place to live.
