Who doesn't understand that services provided by the government comes from taxes? The point of contention is if particular needs are best provided by the government, not if money magically appears. 

However, I do know that I would not be for an education system that has as a priority cracking down on elementary-aged kids exercising their right of freedom of speech... or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. Hopefully that sounds somewhat familiar to the letter-writer.
