The poor pay more for everything, from rolls of toilet paper to furniture. It’s not because they’re spendthrifts, either. If you’re denied a checking account, there’s no way for you to avoid paying a fee to cash a paycheck.

If you don’t have a car, the bus fare might eat up the change you’d save shopping at a larger grocery store as opposed to the local corner store.
