more willing to take risks

I am not so sure the romantic notion of being a risk taker is an admirable one.

By definition, the more risky an enterprise is, the greater the chance of failure.

Hence, most risk takers will be failures, and the bigger the risks, the more the failures will outnumber the winners.

Sounds like a disastrous strategy for nurturing a society.

I don't believe taking risks is the way to succeed.

I suspect that is a line fed to us by the elites, to cover for their succeeding via connections and insider info.

Sure, some people will take risks and succeed, but for every one who does, there must be many more who fail.

No--I don't believe in risks. I believe in knowledge, and I believe in someone who has the clearness of vision to see an opportunity and not be deterred from that opportunity by succumbing to the herd-like thinking of the people around him.

"some people will take risks and succeed, but for every one who does, there must be many more who fail."

Good.

So we can start by thinking of how many entrepreneurial successes it takes to grow an economy and then multiple that by a large value to get some idea of the size of the entrepreneurial population pool we need.

Seems you're thinking it's going to be very big number. Maybe it's best to develop an "efficient" immigration policy were "efficiency" is measured by the difference between the percentage of the immigrant population and the percentage of the general population who are willing to take the necessary sorts of risks?
