I don't actually care whether CGs and dividends go up.. I just believe the path forward requires cuts and taxes. We were doing fine before the 1981 cuts and don't appear to have improved with them. I think the wealth gap was rapidly widening with dividends and CGs were 20% - so double hits, drags, whatever the wealthy were doing just fine.
Bottom line, we can afford national health care and a modest social security safety net with the 1% continuing to thrive. It will admittedly involve some substantial health care reforms (which I don't see coming soon). It will also require some sacrifice by the "normal well off" within the 99% (e.g. my current level now that I am ERd)
Something along the lines of letting all of the tax cuts expire when the economy stabilizes. Alas, I am not optimistic. I think we will break things worse than they are and nobody but the upper 5-10% will come out thriving.
