(To go off-topic for a minute: this is a common problem. When I suggested that welfare systems be abolished to help the poor, a rather innocent, yet grossly uninformed individual of the stereotypical liberal
school of thought responded, "But the welfare system is barely working now as it is, and you wish to take it away?" The idea that the system itself is flawed never struck her - nor most people who believe in it. Rather, they think that we aren't sacrificing enough to keep them running. It is the same with public education; if the system is losing a lot of money and the education quality isn't the greatest, most people assume that it's the people that are flawed, not the system. To make
that error is one of the costliest - and most dangerous - errors one can make in this field. It never can occur to a lot of these people that there is a possible world where the current "private" option would be reformed, too. )
