What exactly is that law? If you charge more than 25% interest on a personal loan then it's considered usury? Is there a certain timeframe on a loan.
My wife was born in TX, we go out there for a month some winters and there are legit payday loan places in every corner out there. It seems like a sound business but when someone doesn't pay its actually pretty hard to get your money back. Especially if they are unemployed and have no bank accounts.
