Credit cards

It appears a law imposing new regulations on credit card issuers will be passed soon. I generally approve of restraining businesses (and others) from taking advantage of idiots as long as this can be done without imposing excessive costs on sensible people. Being sensible I pay my credit card balance in full every month. The new law doesn't appear likely to raise my costs significantly so is unobjectionable in that sense. On the other hand I don't think it actually does all that much to protect idiots from themselves. That would require more significant and controversial measures like interest rate limits, higher minimum payments and the like.
