Each time it has been tried, the unions have sued. They have said they are simply trying to protect public schools. Given this organized opposition to vouchers, the best way to attack the competition problem is through an expansion of the already existing charter schools. These are schools granted charters to operate by either state or local school districts, depending upon jurisdiction. They are excused from many of the bureaucratic rules that have grown up around education.
Most charter schools get results.
And they get them with poor and minority students who usually don't perform well in public schools. The education establishment says competition will destroy public schools. If they were doing their jobs, educators wouldn't have to worry.
