"Progressives" like to keep the poorest kids in the worst schools, keep these schools afloat, wring their hands over the state of the cities, and complain about earnings at the low end of the income distribution. Here is their latest victory. They seemingly resolve the dilemma by offering to ever spend more on the public schools (and the folks who routinely vote for them). But this has not worked.
It's worth adding that this crowd thinks of itself as the most compassionate as well as the most intelligent as well as the most high-minded. The last I heard, they have no trouble sleeping at night.
