Yep, zero. That's the same number as we have bad universities. How many do you have? I've read a research paper by phd professors of one US university and it was so shit that I didn't know whether to laugh or cry. It was even more wrong than most of your statements here.
But sure, let's talk about top universities and why they might be where they are. It comes down to the population. USA 327 million , Finland 5.5 million. Let's say the intelligence was equal in both countries. You would expect to have 60 high quality universities in US for every one in Finland. Then if you form the unis in a way that the most intelligent people go to the number 1, then the next ones in intelligence ranking go to number 2 etc. There wouldn't be enough people in Finland to make it to the top. I hope this example is clear enough that you understand the point, which is that number of top unis is a bad estimator.
Furthermore, comparing universities is quite hard. High quality research doesn't necessarily mean high quality education and good post graduation success has more variables in it than just the quality of education.
