Sure, but we don't make judgements on individual data points. The Soviet Union with the short Fischer interlude dominated chess entirely. Today Russia still averages the strongest top 10 players, India and China have risen to become the third and fourth strongest chess nations within a generation or two, and looking at immigrant engineering talent in the US paints a pretty clear picture as well.
And the educational divide globally and development of science excellence pretty much only grows. How is this even a discussion given the evidence, any countries around that run on 'aristocratic homeschooling'? Saudi royal family kids in Swiss private schools?

And yet here you are making a judgement on the effectiveness of a method of education purely based on the single datapoint chess.
But leaving the hypocrisy aside, I don't think chess is a good example to begin with. The reason why Russia dominated chess is because chess was there a lot more popular compared to other countries. That this theroy likely makes sense is supported by the rise of China and India with their massive population compared to other countries. Having a high amount of interest and good education are components that often reinforce eachother. More opportunities to learn and compete with strong players improves ones own skill level.
Why was there a higher interest in chess in Russia? I can only guess, but I would say the long and cold winters that make outside activites impossible most of the year play an important role.
On top of that the world chess rankings are actually quite diverse since the rise of internet chess. Russia only has a single spot in the top 10 strongest players. [1] The rise of video gaming that competes with chess for indoor mental activity has probably something to do with that.
