but they produce 0% percent of the wealth!
Where you are getting confused with doctors receiving medicare, recipients of federal funds and such is just the immense and deliberate tangled web of redistribution of wealth confiscated from those that produced it.
There are NO "Federal Funds" only funds that have been taken from those that produced them in the first place.
Take ten people on an island. Seven of them work to produce food and shelter. The seven also donate (taxes) some of the food and shelter to the other three who provide "public sector" services. It's clear the other three could not donate (pay taxes) any food or shelter because they have not produced any. Lastly, If the first seven quit working the other three have no food and live out in the cold whether they continue to provide their services or not.
Is your point that the federal government and/or all government must be eliminated entirely because it is the product of the redistribution of wealth thru taxation?
