I agree that a binary gifted/nongifted is not really descriptive of reality or useful.

No kid should get special treatment; every kid should get treatment appropriate to their level. It's not even strictly speaking a matter of resources: you don't need fancy equipment to teach a more advanced class. It does mean you need more teachers and a larger school, so that people can be placed into classes of roughly equal levels of ability.

Then there's only 1 solution: 1 teacher per child. Half that would make the education budget exceed the total tax income of the state ...

Or put differently: for this suggestion we can't pay. And we choose not to pay for even mild improvements to the current situation.
