Of the versions you showed, the US version is for Vista, and the EU version is for Mac. Of course the Mac version is more expensive. It's for Mac (which means people will pay a much higher price for the exact same product even if it doesn't work as well as on competitors hardware; also development costs are spread across a smaller marketbase thus raising price), and its in the EU (which means it has VAT). Meanwhile, the same product comparatively, when both version are for vista, shows http://www.amazon.de/Adobe-Creative-Master-Collection-deutsch/dp/B003FSSL5K/ref=sr_1_1?ie=UTF8&s=software&qid=1273780415&sr=1-1
The Vista EU version is 1784 Euro, which is 2230 USD. Its cheaper in Europe for the same product.
This, by the way, is a fairly niche product that hasn't been released yet, and due to its price, will only be purchased by those who have a very real need for it. No one is buying this unless they already have a way to profit from it or they are super rich and spend their money on software instead of cars and vacation houses.
If you don't like European software laws, set up your company in the US (business registrations are along the lines of $250 a year, and if you can't afford that but for some reason need $2500 software packages, you might try another line of business, for example not having one) and set up a European subsidiary that has to follow the software of the parent company in order to gain work. File everything under US GAAP and make sure you have a residence. A US citizen in name owning the company probably wouldn't hurt (keeping you as either an employee or a [non-general] partner. At any rate, keep the liability in the US, and you can use US software no problem. On the other hand, unless you are a fairly large (publicly traded or on the cusp of doing so) company, hiring expats for the sake of saving money on software doesn't really make any sense. While you *can* do this, it definitely won't be worth the time or effort.
