Not from a product mark-up standpoint. If I want something and it's only made in X country, and that's the only game in town, a variable portion of my mark up will go to "economic rent".... Pricing is about "what the market will bear"... if "what the market will bear" is greater in the European market than it is in the US market... that's the price.
Perhaps a better example are DVDs and the whole "region" thing. DVDs cost pennies to produce, the US consumer pays $20-ish per title for major releases domestically. China is a huge market but they ain't spending a week's worth of wages in their economy on a DVD, so in their region the same exact DVD I paid $20 US for cost the Chinese $1.50, or whatever.
The intitial post suggests Adobe is treating the Europeans unfairly or is discriminating. Far be it from me to defend any SW giant, but in this case it's just not true. This kind of thing goes on all the time, pricing discrepencies - some rather significant, always exist between domestic product and import items for a variety of reasons, some political. You pay more for US software, we pay more for your _____ product. It's about what price a market will bear, business is business... If Adobe would increase revenue by lowering price in Europe, -snap- they'd do it in a heartbeat. Wanna lower Adobe's price? Quit buying their software. Watch the price sink like a rock.
