I agree with you. "Easy" is very subjective and to be fair, I never said that meeting any of my 3 criteria was going to be a walk in the park.
Just getting a visa to work in the USA like I had to do is hard and disqualifies most of the planet (~7.7 billion) people.
Getting into a decent, internationally recognized university is also difficult and likely filters out a huge number of people.
There are several employers paying that much to select from, and companies will reinterview you in a year after a semi-random false negative, so the false negatives are not really a showstopper.
4) Manage to not be a semi-random false negative
There's still the issue mentioned in your GP that there are not that many of those jobs out there to begin with. Also, there are more people who want them then there are slots.
Note that I agree about not needing to get political to get these roles. I just disagree about how easy it is to obtain them.
