I can tell you with 100% certainty that government regulation would have absolutely no benefit in this sector with plenty of potential for damage.
Since the credit industry is heavily regulated already it doesn't seem to have hurt the FICO folks much? They all have lobbyists anyway so they can write the regs however they like.
If we had any real decent regulation it may be something along the lines of "Hey, the credit history of our citizens are their "papers" as noted in the constitution and they have a right to privacy. So why don't you just quit compiling their information without their signed consent?" Or at very least they should be sending each person a check for $20 per year.
Thing is while I may have signed a consent when I took out a loan on a car to report payment history to the credit bureau, I never ever signed a consent for the credit bureau to sell that information to anyone who wanted to buy it. They have laws now about girlfriend pictures. It is alright to take them with their consent. It is not alright to sell them and publish them. Maybe not the best analogy but private is private in my mind.
Same goes for all these internet data bases tracking my every move on the net and then selling the data. Wrong, Wrong, Wrong!
