Government Issued Credit Card?

Consumerist.com unveiled an idea today that I haven't seen before: a national credit card.

I'm really torn to be honest.

On one side, you have the massive savings, lack of hidden fees that are meant to screw you, and who knows what other missing piece of capitalist dog policies.

But on the other, you have a concept that could be catastrophic. The government's role is to protect the country through creating and enforcing laws throughout the nation. If the government is providing the service itself, who would you have enforce you if someone made a mistake?

This is prevalent in places such as the police. If you were NOT speeding in an area, but a police officer trying to make quota pulls you over and wrongly accuses you of this, who do you call? You can't call the police. Why would they trust you more than their own officer?

Also, from what I know, this would destroy what little umph our economy has left. Moving everyone over to a public credit system would invalidate the private system we have, causing way more layoffs and market drops. That is -- unless they're nationalized a la Fannie Mae & Freddie Mac. But tell me this. Since when has the government had better results at running things than normal private institutions that are NOT taking advantage of their power?

There are a million things to question and ponder with this idea. What do you think?
