This isn't a bad idea...but Thomas Sowell addresses this issue in his book "Basic Economics". Banks don't open branches in the neighborhoods where check-cashing outlets thrive because there is no incentive to do so. Costs are too high.
What the heck is keeping people from going a mile or two away to a real bank and opening an account? Nothing.
Maybe government ought to make it worthwhile for banks to do that--but instead government tries to blame the banks for offering loans and accounts where they make a profit. (Profit is baaaaaaaad according to the left!)
Look, it would be great if poor people participated in the economy and learned about how the economy works. They might realize what a PONZI scheme Social Security and welfare is. Rush Limbaugh has been saying that for YEARS. Nice to see the impeached President and the liberal RINO from Kalifornistan figure that out, too.
Payday lenders/cash checking firms may be a steal, but they are the price you pay for letting thugs rule the neighborhood.
If the risk of armed robbery in an area is high, then the locals get stuck with payday lenders.
