You are correct, but it only makes business sense if you can mitigate some of the inherent higher financial risk that comes with doing business with poor people. That's why it's a fee-based structure, and that's why the fees are so high -- they have to offset the statistically-higher percentage of poor people who (for whatever reason) don't / can't hold up their end of the bargain -- by trying to cash bad checks etc. Many people blame the banks for this simply because "the banks are evil," but in reality, that's why interest rates for people with low credit scores are so much higher than they are for people with good credit scores -- there's a direct correlation between credit score and lending risk. The less risky borrowers are more desirable potential customers, so the banks compete for them by offering them a lower rate.
I do agree that this country needs to have an conversation about the growing number of poor, but it must be an honest conversation -- one that acknowledges that sometimes the poor are exploited by lenders, and also one that acknowledges that it's risky to lend money to poor people, because they're less likely to be able to pay it back.
had good interest rates
This is because historic interest rates were insane at the time -- the highest they've ever been. When you bought a house, your mortgage rate was about the same as the one you have when you run a balance on a credit card today. Can you imagine buying a house with your credit card, and running that balance for decades? That's what it was like -- so be careful what you wish for when pining for the 80s, especially regarding interest rates.
Ahhh, so you're willing to vote for evil just so "your team" wins. Except that you haven't figured out there's only one team -- Team Status Quo -- and you're not on it.
You're a coward, and absolutely deserve every nasty thing Feinstein inflicts on your state. You have no principles -- only a tribe. People like you are why this country is fucked.
