Don't confuse the internet situation in Germany for the internet situation in the whole of Europe. Some countries have cheap data, others are unreasonably expensive. European internet infrastructure isn't as homogeneous as people seem to think.
Here in the Netherlands, you've got national coverage with unlimited data for €25 per month (practically unlimited, not theoretically unlimited, of couse, because fair use policies exist everywhere).
One country to the south is Belgium, where even the landlines have data caps, something that would be unthinkable here.
There's some connection between GDP/purchasing power and the price of data, but there's much more going on. Things like nationalised internet connections, government investment in public internet infrastructure and geography are more important than how much money someone in a certain country makes on average.
