> Also due to how Europe is wired up, the cost of doing startup business is higher, why there are fewer and fewer successful European software growth companies.

I really believe the primary reason is that Europe is not one culturally homogeneous area that speaks one language - like the US. Having that is such a huge benefit.

Doing marketing, promo, getting traction, legal documents, taxes, - anything - for your startup in your ONE country is already difficult. Now imagine doing it in 25 countries before you get to have scale benefits equal to the US or China.
