Try to talk with the devs. Maybe they can do something if he provides them with copies of the moneytransaction and his id. It's not the rule, but worth to try.
I've had that too once, they even wanted to kick out my door. They were looking for the former renter of my house. I guess he didn't check out, also got lots of mail for him
Even Bush now confirmed there is a problem. So it is already started.
I don't know what effects will be outside of USA. It will have effects, because the dollar is an important currency on which a lot of the current economy is based.
For USA people it means they can't leave the USA because their money is worth nothing. But it gives opportunities to grow again. A lot of people over here order stuff from the US because it's cheap now (that is Europe money spend in the US what is good for the US economy again). From the other side, China has that same opportunities for the same reasons and US can't compete with that (Chinese economy is growing and American economy is falling)
4.35 per gallon for gass is not expensive From an outside view, i think a lot of the problems with US economy are because of people living above what they can afford. You can see it at the houses. The houses look great from the outside, but are made of wood. You have program's on tv of House Metamorphoses where people are send away for an afternoon after which their whole house is rebuilt. The house looks great, but it are only a few wooden walls (with the balcony already attached). Great house from the outside (looks great for the neigbours), but only made of wood and not very solid. It's the same with your cars. They look good and are very big but after 200.000 kilometers they start falling apart.
A dutch guy had a very good compression idea that saved a lot more then the regular compression methods. He got investors and started working on it, but died along the way before it was launched.
Someone tried a few years later to discover what exactly this new compression was (from old-news and interviews with the deadguy). He found out the new part was he combined compressed files which did a lot for the filesize (it was more then that, but that was the biggest factor in increasing the compression rate) because then there is a lot more to compress. Only problem is you can't use that online. You can't send one file because you need the whole archive.
