Slightly off-topic, but coming from a country where credit card interest rates are around 15% _per month_, I was amused to find people complaining about 22% _per year_ interests in North America.
I imagine rates are determined largely by the general state of the economy (if you currently have a job, how likely are you to lose it?), the amount of data the creditor can gather on potential debtors (what are your wages and current debts?), and the credit card company's ability to efficiently collect on debts.
I wouldn't be surprised if the collections process is easier in the US than in other countries. The economy is not great right now, but credit card companies can also limit your credit to make sure that you don't borrow more than they expect to be able to collect later. And they can see what your existing debts and monthly payments look like, which allows them to de-risk their lending.
I would guess that consumer credit is much looser in USA than many other places. Like I had changed a job and couldn't get a credit card with 1000€ limit. Automated system simply blocked it.
This looseness is great boost for economy, but on other side it also means credit risk and thus the interest levels must be higher to in general to cover those losses.

But it sounds like US interest rates are lower than some other places, based on GP's comment.
