Someone who pays no taxes and does not contribute to society is either grossly handicapped in some way, or is a parasitic leech living off the life blood of society.
Someone who is forced to hand over all their earnings at gun point is a slave, no matter how you look at it.
Where is the dividing point? Where does it go from 'Okay' to tax that much and become slavery? Where does it drop from 'taxed enough' and become parasite time?
How much do YOU pay in taxes to support society? Where do you fall on that scale?
