I disagree. Do you believe this is the case today or is it the goal? From what I understand, the gap is quite large between number of small companies based on environment. Many of us with smaller companies stand on the shoulder of giants. Sometimes you have to take the bad with the good, and that can mean the financial incentive to become large spurs those of us who are small. Artificial ceilings, however altruistic people tell themselves they are by limiting the big, bad, scary companies, often are just a low tide lowering all boats in a trickle-down way.
You're right, but what I was saying is that I believe it is the case today in the EU to a far greater extent than in it is in the US. That's not saying in any way that the EU is close to an ideal situation, or that there aren't big, dominant EU players. Along with the case of the influence of big non-EU players skewing the environment to a large degree.
You're presenting the situation as a failure of the EU, but I think you've missed the point here. The big players are located in the US because the environment there rewards big players and has a general snowball effect. The EU system rewards small-player innovation and limits the creation of very large, dominant, monopolistic big players. This should be a net benefit to the overall system, if it weren't fot big players just coming in from elsewhere. Unfortunately, due to the global nature of the web, this leads to less-regulated US big players dominating the EU players. Solving that is tough, but the fact GDPR applies to US companies is an interesting start.
