Yes, Medicare, I know the difference and just mixed the two.
you didn't experiment that dropping the 47% to 0% would have negligible effects - because you forgot to factor in the concept that the majority of the 47% are net negatives. In order to pay $1 in taxes, you must first give up the amount that you benefited from our tax system. Nice try though.
Social security and medicare go to defined pools. They don't affect the deficit in any way, shape, or form. So no, you can't factor those in just like you can't factor in State income taxes or state sales tax.
Lets do the same. Separate defense tax, agriculture tax, science tax, etc into separate defined pools. Then we don't have to factor anything into the budget! Good job, s0me0nesmind1, problem solved. Or, you can realize that they are not actually in separate defined pools and you can't just ignore the problems away.
The majority of the 47% (46.4% actually) are not net negatives.
* Many are back on the payroll. That 47% number came from near the peak of the recession.
* 22% of the whole population (just under half of the 47%) are retired. And if we go by your definition that their needs are in separate pools (social security and medicare), they shouldn't count.
* 18% of the whole population (just over a third of the 47%) are the working poor. Thus they do pay substantial FICA and sales taxes and usually don't qualify for much of welfare. So their net taxes are roughly $0.
* You are left with only 7.9% of households that are net negative.
