Frankly, the biggest difference between USA and Europe is that USA is comparably homogenous market, especially in high-tech, whereas EU even with common market isn't. It also means that Micheal Dell starting a company building computers in garage from parts, like many many companies in just in Poland, let alone EU, he had ready made, near-zero extra cost, market of 235 million people that spoke effectively the same language, required no export declarations, and had nation-wide ways to market. This is a real differentiator. BTW, China is internally very very competitive, though it appears they put focus on smaller companies than big american style corps (even though they have such as well, obviously)
