We can't fire incompetent teachers ! the unions won't allow it. There lies the problem ! That's why the voucher system was introduced, to draw demand away from bad schools with bad teachers that are protected by....the NEA. Simple economics, ever heard of 'supply and demand' ? ( probably not if you are a product of a poor public school )
There was a study done awhile back on amount of money spent on public schools, it showed school districts that spent more money per student provided lower education while schools in smaller communities with less funding provided a better education. Proves throwing more money at the problem doesn't fix it. HMMM...maybe family values and less government may have something to do with that ?

Yes illuminating the unions would lower some wages, bringing them in line with the private sector wages. The largest union in the country is the federal workers, why do you think our government is so incompetent ? Even a product of the public school system can figure that out !
