As these things go, the plan was eroded over time, with the (in)famous Proposition 13 of 1978 dealing a big blow.

What saddens me is that grand (and simple) plan "free education for all" gets watered down and chipped away to "free education for those who have money or connections" and later attempts to shore it up offten amount to "free education for $special_group". While I don't deny $special_group should get free education, what gets me is all the special-pleading going on.
In OOM programming terms, it's like we had a universal principle which was easy to implement, and this has now been replaced by a bunch of switch/case statements...
We all know what is meant by "free" in this context, and there's no point in acting obtuse about it except to argue in bad faith.
In the case of covered education for foster kids, I’m conflicted. I’m in favor of providing anyone placed in the foster care system resources to offset their hardship. I would support non-profits that showed they could efficiently direct funding to programs to help foster kids go to college. I would wager there is research that shows positive economic and social impact by sending foster kids to college that outweighs the cost and significantly reduces the risk of foster to prison. But that’s my choice and don’t think everyone else should be forced to have the same convictions.
While not perfect, Arizona exposes this somewhat by offering tax credits for contributions to non-profits in certain categories (aid for working poor, tuition assistance, foster/adoption, public schools). I’m still forced to cover the cost of social programs, but minimally I get have some agency in choosing organizations that align with my philosophy in those domains and aren’t kicking back a slice of that money to politicians.
Many compalins ignore the costs of missing these services.
We have 'free' firefighters because entire cities used to burn to the ground. That's very expensive to rebuild.
We have 'free' sanitation becauae The Black Death did more economic damage than both world wars combined.
We have free school education because having a population that can't read and write is economically ruinous. And politically ruinous - illiterate people can vote, join cults, maybe they support the inquisition and burning witches at the stake. We've been thought that.
No-one i ever met believes we should go back to the times where majority couldn't read and write becauae parents could not afford school. Some just believe that education stops at an arbitrary age.
