"It’s a series of measures that basically say that seniors, middle-class families, disabled kids and others will solely bear the burden of buying down the sequester while the weathiest get held harmless." (emphasis added)
The key word there---and in so much of the administration's statements on the issue--is "solely." What they mean, then, is that it is perfectly okay, in their minds, to make seniors, middle-class families, and disabled children partially bear the burden of corporate greed, military adventurism, and Wall Street recklessness. That, as I see it, is also unacceptable.
