It isn't that it is impossible to get a utility-grade education from a public school, IF the parent will be involved in their child's education.
The problem is that you kid will spend most of his time around other kids whose parent(s) is(are) potential Jerry Springer guests. He will learn concepts that young minds are simply not ready for. He will be taught to doubt his sexuality before he even becomes a sexual creature.
And to top it off, you will be allowing a large, self-absorbed bureaucracy into your life and the life of your child.
The morons who can survey the state of public schools and vote for property tax increases (some 2/3rds of the populace) may be irredeemably stupid. New school buildings are becoming architectural masterpieces with every luxury simply because school districts (in Texas) are extremely cash rich.
And even that isn't enough. In the midst of huge revenue windfalls due to massive property value inflation, they are raising tax rates.
Their greed is unchecked and out of control.
I can't do anything about the fools who vote more taxes for themselves to pay for this insanity. But I don't have to put my kid in the middle of it.
