The worse alternative is sleeping on the streets when you can't pay your rent. While I do think payday loans are evil, I recognize why they exist. I would prefer a much more robust housing support system for lower income people. Almost all of society's problems could be fixed with more affordable housing. For example let's say you have abusive parents, if affordable housing exist the moment you turn 18 you can up and leave. But now you have bizarro programs which will stop you from attending college if you get "affordable housing"( government subsidized). When I was young I was able to find a $600 apartment, on the free market. Now the same place is 1200$.
On the other hand, rent-a-centers are disgusting. I remember when I was a kid I had calculated they wanted me to pay something like $3,000 for a $500 laptop. But the idea is you only need to give them $50 a week. I went and saved my money and found the absolute cheapest laptop I could, paying cash for it.
On a larger level, car loans are also extremely exploitive. No one needs a car which cost more than $20,000, but all these shiny ads show girls will swoon over you, men will respect you, as long as you buy a car which is $75,000 + tax and destination.
