"Radical" would be too kind a word. Try "UnAmerican" or "Unconstitutional". The vast majority of government employees work very hard and they all pay taxes just like everyone else. No taxation without representation ...and they get to vote on representatives just like everyone else.
Anyone else paying money back to their employer is called a kickback, Government workers do a kickback and pass it off as paying taxes. The money flows out of the pot and right back into it, a mere exercise in smoke and mirrors, but it is not a tax. Taxes are collected from the private sector.
