I disagree largely with a system driven mass consumerism and capitalism
Maybe lots of (most) other people like consumerism & capitalism? And would resent you for imposing another value system on them.
Look around, electricity, Internet, well-insulated houses, Cars that talk to you with high safety standards, evidence-based medicine, high standard of comfortable safe living: this stuff came/comes out of the capitalist system. We could tweak a lot of it for the better, but doesn't mean whole thing is rotten.
which builds an ideal of conformity and success judged by wage or financial output.
Yet our culture celebrates the different. Ellen MacArthur, Bob Geldoff, Eddie Izzard, Claire Short, Donald Trump, Danny Boyle, Bill Gates. They all have done quite well out of being mavericks in the capitalist and consumerist system.
children not starting school until 6 or 7
The countries that do this well tend to be culturally homogenous (e.g. Scandanavia) with high social conformity AND free preschool /nursery from 1yo. Not so individualistic.
and a curriculum led by teachers...
I mostly agree with you there!! With some kind of checks, though.
Yet Our democratic process came up with something rather different. I know people who get really depressed about the rest of society holding values they despise, or patronise the electorate as stupid or deceived sheep who didn't know what they were voting for. I don't know how folk get thru each day with such a negative outlook.
Sounds like OP would love HE.
