I think Start-Ups as understood in the USA is also strongly connected to the peoples philosophy and culture. Knowing a little about the German and UK start-up scene, I feel that European entrepreneurs and investors favour a more risk-averse and engineered approach instead of the "let's do it and get rich or die trying" approach I feel is more common in the US. Just applying the US approach to another country where people think and feel totally different about the topic of founding companys can't work. But why should there not be other approaches that also work fine? Of course they might not lead to the same goals, Steve Blank has defined for a Start-Up-Ecosystem, but why should they? Maybe less innovation and less compensation might be okay, if you get also less risk for example.

You're assuming something about the value of the innovation and the cost of the risk.
Would you be willing to pay 1000 failed startups for one Google? I would, because the cost of those 999 startups is largely borne by the folks involved while I get significant benefits from the existence of Google.
