Conscious, complicit, calculated tax policy is what lets them get away with these things. They call it a game, using lobbyists, accountants, lawyers and cash to make indifference legal. By being a nation that permits a game like this, we have collectively lost all honest moral compass. This institutionalization of policies that prove to all the world how little the US really takes care of its own people is tragic.
And the Public Education situation is merely the example of the week. In health care and its provision we do just as badly for all the merely greed-bound reasons. In human rights issues and issues of inequality it's all the same. Sadly, these things are only news because they still persist. The continuing recitation of specifics may be new information, but the politicians are not operating differently.
In my view, it proves the failure of the US Constitution that representatives will only represent the wealthy and their artificial entities.
Consistent practices make the laws into an embarrassment and those who benefit make themselves unaware when facing the public. Such consciously myopic indifference really shows the true colors of the lines of difference we all need to see in order to know who we collectively are.
Embarrassingly shameful in a world and time when there is no legitimate excuse not to require that our public officials admit they know how we can collectively do better, and that we could even be doing the right thing in all these areas.
