but that is not feasible for mass majority of people in our society. That is why public offering is so important and that funds aren't diverted from it, because we can give opportunities to all students no matter the financial situation their parents are in.

It doesn't work out that way though, public schools in wealthy areas are much better than in poor areas.

Equal funding mandates don't address cost differentials, and poor people often live where key education-related costs are higher (e.g., the cost of getting good teachers to work there, as the areas are less attractive to live and farther to commute from places more attract to live.)

And some states, IIRC, don't even have equal funding mandates to start with.

I didn't even know some states have an equal funding mandate, where I live the rich kids go to schools that look like castles and the poor kids go to schools with holes in the ceilings.

Equal funding mandates, where they exist, often address operating funding, not capital costs.

Of course, infrastructure quality effects operating costs, so there is a source of inequality right there.

Interesting. My high school looked like a prison. No idea if it's true or not, but some students said the architect did both.

It is not available today, but do you think it would be infeasible if somehow it is agreed to be "The Right Thing" to do? If so, why?
