Charter schools and vouchers are spreading rapidly across the country because they give parents a choice to opt out of failing public schools. They are most desired by minorities, whose kids are stuck in the worst schools, staffed by the weakest unionized teachers who cannot be fired despite their proven incompetence.
Many of the comments here are from people unexposed to such teachers and such schools. Better neighborhoods naturally have the resources and teachers that deliver a better education, which is why vouchers face an uphill battle. But if one is concerned with the abysmal ranking of ALL our students vis-à-vis other developed countries, one has to challenge the status quo dominated by the unions.
