You are missing the point. For a society to work, it's members have to perceive it as somewhat fair. The naive idealist would demand equal opportunity for everyone born. But we humans want to use the means available to us to directly improve out children's opportunities. Our freedom to do so makes our society inherently unfair. Especially when we expect those "investments" like education to pay for themself...

The interesting question is, like always politics, how to balance those trade-offs for bests outcomes.

Yes, that means both giving parents the chance to help their kids while also not having a disillusioned crowd without perspective demanding to tear down society in favor of whatever promises to be better. And yes, that requires some degree of wealth redistribution like decent public eduction.
