The fish rots from the head.
In India it's purely score based. Top on the JIT (although I guess they have special things for scheduled castes or something), you get in. In Sweden the same. Top 1% on the högskoleprov and there's nothing you can't get in to. Maybe KTH has its own, more advanced maths test for entry, and I think you need to pass an interview for medicine at KI, but aside from that nothing you can't get into. At ETH they see whether you can pass a first year of courses.
But in the US it's a bunch of weirdness, and it's from Idpol. I don't know if you could avoid it-- India obviously doesn't want to avoid it completely, but another idea is to not have the arbitrary eliteness be a thing. I used to believe in something like it, believing that only certain Swedish universities were okay (and that's probably still true for education), and then a bunch of Germans who wanted to be professors got jobs at the ones I thought were shitty and started doing good research and suddenly you ended up with places like Örebro, which I had regarded as 'what even is this' producing real science. I think the Germans are right and that a distributed less status-based university system is sensible.
Would you say the same about Independent University of Moscow or about or the ETH? At least IUM is obviously better than Harvard. I don't have specifics about Harvard people, but I know that the Chalmers people I know have a higher average level than the Ivy League (none from Harvard) people I know. I have no comparison of the KTH people and the Chalmers people, but in theory the KTH people should be better, because I've never been in a workplace with both the KTH people and the ivy league people, so I can't compare them.
The core thing though, is that people in the US who want to get into these schools have to do hoop jumping. For these Swedish schools hoop jumping makes no sense, because you'll get in if you're academically sound enough, so you can actually focus on academic soundness, so you do.
