Building more schools for the children Americans don't have
(but flow over the borders daily)
It more and more reads like California is dominated by slush funds for various business interests.
Developers don't pay for schools. Buyers pay for schools. In this case, the protected class is the local home buyer.
The relief being sought is to shield new buyers, with children, from the direct expense of building public schools for their children. These buyers are expecting that other taxpayers, from across the state, will ameliorate the direct, financial consequences of their personal decisions.
