Doesn't matter. Rich enough to afford most products, as pretty much the only market other than the US. And more people. Biggest addressable market for most things.
So what? Even people living in poor EU countries buy iphones, use windows, watch Netflix
If the market was at best 1/3rd of the US no one would bother implementing all these regulations
And yet Apple, Microsoft and Netflix make significantly more revenue from the US than the EU. It's almost as if the EU is not actually a bigger market.
Even users from "rich" EU countries are worth ~30% of a US user to most companies.
