Take a leisurely stroll through the history of American enterprises that have come and gone, that started out with high hopes only to crash and burn on bad management, under capitalization and changing times, one quickly realizes that private effort is as susceptible to all the faults and failings that plague the public sector.
Private enterprise offers no solid guarantees on success. So, let's not have a silly love-affair with Charter Schools, as if they could do no wrong, as if "privatizing" public education is the cure-all for every problem. It's just not true, in spite of the jingoism of Wall Street Devotees and those who hate all things public.

The same standards that others have applied to public education must be applied, now, forcefully, to Charter Schools. If they're failing, find out why. Try to fix it, of course. But let's not be afraid to cancel the charter - either going back to the public system, or granting the charter to another corporation. After all, isn't that the American Way?
