Awhile ago, there was a post showing that the rich, very rich and super rich pay much of what the US takes in, as if they were somehow more deserving than those who contribute their 'widow's mite'. Clearly US taxpayers as a whole aren't contributing enough, or there'd have been no Debt Discussions Crisis recently. Of course there are still those fairytale believers who think some magic legislator or swivel servant will do what's never in recorded history been done before and bring them a government that lives within its means, because they've cut taxes, leaving the spending to be cut by those magic folks.
But for us rational folks, given that half the taxes in that post came from people whose income was $38,000 or less, who else has the ability to pay more if not the Buffetts and their ilk?
