Also, among those who aren’t willfully ignorant, it’s well known that increasing resources increases inequality. The classic example is height: when resources are low everyone is short. But when resources are plentiful then those with the genes for height tower above those without.
There is absolutely nothing wrong with that.
Those who were short didn't fare worse in absolute terms. They only look worse off by comparison.
Essentially, if something is a zero-sum game (e.g. there are only so many jobs around, if you get a job someone else won't), then even if someone isn't doing worse absolutely, they can still do worse overall relatively speaking.
Which isn't to say that we should be giving short people stilts and cutting the legs off tall people, but it's worth recognising that these topics are complex, and even if we're only talking about absolute benefits, people can still lose out relatively speaking.
My obligation is to my children. I'm happy to entrust them to a system if I have faith in it, or the people running it. If I don't...it would be downright irresponsible.
In reality, the political leaders in charge of this societal reordering will themselves become the next upper class, and you can bet with certainty they'll give their own kids the best education and opportunities they can (which will be better than what they offer the masses).
