Ok, allow this resident of one of those Eurosocialist hellholes to chime in. I see two typical misconceptions about Eurosocialism (aka social democracy) sticking their head up again. One is "The pay is the same whatever you do", the other are the infamous health care waiting lines. Both are patently false and confuse the European system with a state economy as found in the USSR. The European system is about enforcing and subsidizing minimal standards and nothing more. Outside of those minimal standards, it's a free market, for jobs as wel as for health care.
OTOH, there is indeed a difference in attitude about entrepreneurship between the US and Europe, but IMO this has little to do with religion or socialism, and is in fact much older than the advent of secularism. Its roots are found in the feudal/aristocratic history of Europe. There's still a subconscious "don't rise above your station"-attitude present in many European countries, even though aristocratic rule has been discarded long ago. This also manifests itself in a disdain for failure: if you do try to better yourself, you'd better succeed or earn the scorn of the community. Having your startup company go bankrupt is NOT regarded well and may ruin your business rep for life. This leads to the sort of risk-averse attitude which is not beneficial to innovative enterprise.
Ok, this sounds worse than it is, it's more a cultural background noise than an ostensive behavior, but it can be annoying. There's plenty of high-tech startups in the EU doing wonderful things, but there should be more IMO. The "can do" attitude, now matter how ill-conceived in some cases, is the one thing I envy the US. Something like the X-prize would be hard to imagine in Europe, and that's a pity. WE NEED ROCKETSHIPS, DAMMIT....
