If you view the federal employee as not really paying any taxes, then what about the private sector recipients of federal funds such as the defense industry, contractors, consultants, etc.? Or the doctors who receive Medicare and medicaid payments? Or the supermarkerts that cash in the receipts from 46 miullion food stamp recipients? The government controls close to 50% of our economy. The $3.5 trillion annual federal budget is paying for more than just federal employee salaries and benefits. And ditto for state and local governments. The line between the public and private sectors is somewhat blurred. It is called crony capitalism.
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.
