Explaining to me that taxing my SS benefit more every year is a good thing because it helps fund Medicare doesn't make me glad it isn't indexed. I feel taxes are a good concept, but I believe corporations and the folks wealthy enough to figure out how to pay little to no taxes are buying congressional protection for their wealth. The Democrats want solvent social programs, and the Republicans want a 50% tax cut, so the Democrats concede for token pennies so the Republicans can walk away with the dollars.
"The lack of an indexing provision for the thresholds was not an oversight by Congress. When the 1979 Advisory Council for Social Security first proposed taxing 50 percent of benefits, there were no taxation thresholds. After this proposal encountered immediate and widespread resistance from Congress, it was suggested by some advocates (see Munnell 1982) that benefit taxation might be made politically more feasible if taxation thresholds were used similar to the ones then in use for the taxation of unemployment compensation. ... By leaving the thresholds unindexed for inflation, they would diminish in importance as the years passed, with the result, as Munnell pointed out, that “as incomes and Social Security benefits increase gradually over time, the revenue gain will approach that of including half of Social Security benefits in taxable income for all retirees."

So you want me to be happy to contribute while being retired on a fixed income with increasing tax burden and increasing inflation. I just can't understand how that is good.
