My only argument/retort is that with a wealth tax of 99%, it would completely, thoroughly and spectacularly fund for the production of large, public boarding schools with twice enough teachers to have low teacher-student ratios, other staff to assist with hygiene and food, etc so that the children were put into exceptionally good boarding schools.
Even if this hypothetical school cost $500M per year to run, it would be worth it to make sure absolutely no children are left behind and with the assistance and means to pull themselves out of poverty.
Collectively, we could be raking in hundreds of billions of dollars per year for these schools, free tertiary education, free public health. We don't need to divide ourselves between imaginary lines of difficulty when making sure our children are educated.
