Well, you are complaining at once about students studying outside their catchment (quality of school depends on willingness to travel), and students studying inside their catchment (quality of school depends on local tax revenues).

The truth is that every system has tradeoffs, not every flaw in each system is fatal, and there is real room to explore.

From some perspectives that could be a good thing, because some places would rather be able to afford to have kids in school every weekday, than index the pension fund for a vote buy. Teachers should work in a market like other professionals. Very productive teachers can scale up, as is clear from success stories regularly seen, for example, in Korea.
