This is PC run amok! If you worked hard to maintain a business would you lend money to a person who has a record of a deadbeat? A credit history is also a gauge of a person's personal responsibility. What next - no criminal background checks for blacks because they have higher crime rates? The inmates are running the asylum!!
I wonder if they do a credit check before you go on welfare?
If the inmates have the political power it will work that way.
It true that the same argument has been made against territories in insurance ratings. The critics would say minoritites tend to live in particular areas and therefore are singled out. But the use of territories has held because if a minority lives in a cheaper territory they will obtain the cheaper rate.
I am sure the people who use credit checks will fight to continue and some of them like the insurance companies have the resources to make a fight of it.
