"... go out and earn it." Erh ...
Some years ago I wanted more money. Looked around, noticed that rich people generally hadn't earned their money but had inherited or got it by some kind of capitalist chicanery.
So I set to on the Forex and UK property market and made myself - and my family - some more money. I avoided (not evaded ) tax as much as possible. I stopped doing all that when I had enough and got a proper job; now retired.
So what? Well, I didn't send my children to private school, mainly because British private schools provide such dreadful education. (I didn't want my children to grow up to be people like Boris Johnson or Rishi Sunak or any of the other old Etonians and Wykehamists and so on.) All my children now have PhDs and serious socially-productive careers as well as good friends, partners and children themselves. So that was a good choice, phew. They seem happy.
And so what else? Just an opinion. One of the reasons Britain is in such a comparatively bad state is its continued apartheid educational system, wherein the kids of the rich go to these terrible establishments where they learn to be competitive and end up caring about useless things like wealth and power over their fellows. Then they finagle their way into power and do bad things.
"... what we need to compete ...": I taught my children it is better to cooperate than compete. I still think that true.
A pp mentioned Finland. It seems to me not coincidence Finland seems to do so well for its children these days, given the history of its education system. (Look it up. Learn from it.)
