Apples-to-oranges. Most European countries have many other obstacles to starting a business. It can be almost impossible to fire workers. Some places have mandatory short work weeks. France apparently has special police that monitor them! There have been onerous regulations about running small businesses from your house. The tax code is different and often less favorable to small businesses. And the cultural climate is "famously" hostile to entrepreneurs.

You can't extrapolate the outcome of universal health care in the States from Europe's experience. The conclusion that universal health care would hurt entrepreneurship (or even fail to help it) remains counterintuitive.

The same applies to Canada. I don't think canadians are more enterprenual than americans

nor as in Canada!
