No, actually. Few, if any of us do want the evil, evil corporations around. Ask a normal person, and they would likely be much more partial to the average, everyday corporation instead. Government has its place too, though obviously not as far spread as your post seems to be implying. Specifically, government should be there to watch over the system, and make sure that corporations don't screw you over as much as they could. In addition, they should provide social services, and coordinate infrastructure development. All things that cannot, or should not be privatized, whether to provide visibility, reduce corruption, or out of necessity, since some of these areas will not be profitable for a company.
Now, please understand that I have nothing against turning a profit. After all, I too work for a large corporation, and understand at least basic economics. If you provide a service, then it is only reasonable that you get something for it. What I am against, however, is the idea that you should be able to turn a disproportionate profit by taking advantage of those not familiar with areas like finance and law as you are. In doing so, you are effectively pooling money that would have otherwise gone to a wider range of third parties. If you are a corporation that engages in this sort of behavior, then quite frankly I consider you worse than scum, and I know you deserve whatever comes to repay you the favor someday.
Now realize, CC companies already charge a per transaction fee of a few percent of every payment you make, so it's not like they have no source of revenue. Given that, what sort of reason would they have to charge upwards of 30% on your "loan". I am not arguing that they cannot, because obviously it happens, instead I ask why is this reasonable? They are effectively making significantly more more on this sum then they could in most any other market.
Further, credit cards are not your traditional loans, which you pay off over a period of time. Whereas your mortgage requires a specific monthly payment, credit cards can easily grow out of your control if not careful, and then continue growing faster than you can pay it off.
Of course, the poor idiot getting charged for this services probably has no clue how to get out of the trap. If you did not realize that living above your mean is a bad idea, you are certainly not going to have the know-how and the background to figure out how to get out credit card debt. The banks are seldom very forthcoming with this information. Sure, you might say, just google it. Unfortunately, many of the people in this situation do not even understand what Google is.
An interesting question to finish off. Why is it that I can get a credit line at the bank that charges significantly less than even 10%, but as soon as I tie a similar line of credit to a piece of plastic, the cost jumps to 30%?
