You can't do anything about it because we don't genetically enhance children. Yet. As of two years ago, we mapped out about 2000 genes that contribute to intelligence. A decade ago, we knew of 100. Another decade or two from now, we'll have it entirely mapped out and we'll start to engineer our kids.
The reason we'll do this is because our enemies will do this and a high IQ population is a strategic advantage.
Its not about "systems" or the status quo. The status quo changes over time, always. Used to be, your ability to throw a spear and kill an animal for the tribe set you apart. Then, what vagina you came out of and what sperm were used to create you designated your station in life. Then, it became your ability to facilitate trade between parties. Later, it shifted to your ability to leverage the output of your fellow man to build a factory or a railroad. Now, in the Information Age, you're limited solely by your IQ, your creativity, and your grit. Those who advanced in the systems above all had grit, determination, willpower, drive. That's a necessary condition and likely always will be, but the other conditions all changed.
IQ will likely be the stopping point, at least for humanity. What happens beyond us, that's anyone's guess.
Unfortunately, you're still falling back into "utopia-vision". You think if we just build the right "system", we can eliminate all this. Not for a very long time. Probably not ever, and if we ever do, we won't be humans in the current sense, because whereas you're concerned with systems, I'm concerned with human nature, and as it we exist right now, human nature won't support any system where billions of people are propped up by millions for their survival. The resentment it generates, on both sides, is simply unsustainable. The "smart" people who generate all the wealth that the rest of society survives on will resent having to work to maintain society, and the rest of society that receives that wealth will resent not having the same quality of life as the "smart" people who make it all possible in the first place, usually not realizing they'd all be starving to death if the "smart" people decided to merely shut off access.
And we won't end up a society of all philosophers and artists because frankly you have to be smart to be a decent philosopher and you have to be creative to be an artist. Most people have middling qualities of both traits. Furthermore, due to the interconnectedness of our global society, people are interested in, can access, and generally are only interested in the "best". Andrew Yang said it best during the 2020 presidential campaign cycle in regards to trying to "regulate" and "break up" Big Tech. No one's interested in using the second-best tech product. Don't believe that? Android and iOS are essentially at parity. You could also say Samsung and Apple are at parity. Almost no one uses Windows Phone OS even though its perfectly acceptable as an operating system and was more than capable of doing what almost every single person needs. But it was the second-best choice, with Android / iOS being the best.
We see how that played out.
I'm afraid we're in a really rough, really shitty ride. I want to be wrong, because if I'm wrong it means a better world, but I'm using the history of human nature as my reference.
