I have the solution..make all 'public' education non-free. Make parents have to pay for their children's education otherwise they get none. Period.

You will not have the problem of having teachers that cannot keep control of the class.

It will make the act of getting an education mean something again.

Actually getting an education will have a positive affect on your income level.

It will make having an 'education' a real viable commodity for the person and give them the ability to get the 'good jobs'

It will force the Parents to actually 'Parent'.

It will lower taxes.

It will make it easy for people who do not want to work at learning happy.

We will all finally have a way to judge each other that has nothing to do with color, sex or race.

Please take my comment with the correct amount of sarcasm, humor and seriousness. I know its a pipe dream but it would do all the things I said it would do.
