Ok you have a valid point but since the article is full of kind of wishy washy questions I didn't feel guilty about adding some more into the mix. The title 'Why is Europe Failing to Create More Unicorns?' has an implicit bias in it. The question is saying that Europeans should create more of these massive new companies. 10 smaller companies might be better than 1 big company. 100 companies worth $10 million dollars…
Thats not what I am saying at all though. In fact I am very open in the essay to the question as to whether it's even something you would want. But the fact is that they have an effect on the world outside the US. Perhaps you are fine with that, I would love to see some more Europeans get into the game if nothing else to boost morality and have more people try and create companies.
If a proportion of those europeans who could run startups hold back from following certain business models then you will get fewer startups overall.
