As others have noted, I'd try to read between the lines here. More entrepreneurs in Europe, but not on the same scale than in the US. Which seems to be a game of "choose one". Higher taxes = bigger safety net for society = lower scale of business and incentive to invest for money moving globally and mostly caring about nominal return, not local job quality. Add red tape and strong industrial lobbies like in Germany to the mix which - especially in the past - limited upwards potential. Less taxes, much more business friendly legislation (contracts, labour) and tolerance towards failure = less individual safety but much more dynamics = lower absolute numbers of entrepreneurs but much higher scale aka mega corps. Add the fact we're living in the time of technology with close to 0 marginal cost of information flows and the power law (80/20) kicks in with full force, allowing digital companies of larger scale to significantly grow further. Compared to Europe, the US perfected that principle.
