That might on how the source you read counted "entrepreneurs".

In Poland, where I live, probably every other adult is an "entrepreneur" these days - people start one-man companies because employers all across the board are pushing people away from normal job contracts towards fake, on-paper B2B relationships. If you visit a grocery store in Poland, then while regular clerks are most likely normal employees, there's a good chance that the shift manager is an "entrepreneur".

The problem is people typically say "entrepreneur" when they mean "VC-backed vaporware tech startup with no business plan". And as far as I'm aware, it's true that Europe doesn't have as many of those as the US.

thankfully europe hasn't followed the us over the cliff of endless VC money and bad business ideas

If your employee "protection" laws make it difficult to start and grow small businesses, of course you'll end up with lots more 1-2 person businesses, and can claim you have more "entrepreneurs".
