Has the US come far enough beyond Brown v. Board for today's Supreme Court ruling to NOT be damaging?

The Supreme Courts ruling is arbitrary and capricious given our countries decade old commitment to equality of educational opportunity. Our country, states, counties and school boards are now expected to make an about face on this issue without the benefit of leadership or adequate direction. I think the irresponsible actions of the Supreme Court are simply a supplement to our ailing legislative and executive branches of government. America is stumbling around in the dark trying to find some reason for existence. We need leaders!
