I was also dismayed to find that in some ways, it is actually more expensive to be poor than not poor. If you can’t afford the first month’s rent and security deposit you need in order to rent an apartment, you may get stuck in an overpriced residential motel. If you don’t have a kitchen or even a refrigerator and microwave, you will find yourself falling back on convenience store food, which—in addition to its nutritional deficits—is also alarmingly overpriced. If you need a loan, as most poor people eventually do, you will end up paying an interest rate many times more than what a more affluent borrower would be charged. To be poor—especially with children to support and care for—is a perpetual high-wire act.
