Welfare State as Slavery

From Walter Williams:

Where does Congress get handout money? One thing for sure, it's not from the Tooth Fairy or Santa Claus nor is it congressmen reaching into their own pockets. The only way for Congress to give one American one dollar is to first, through the tax code, take that dollar from some other American. It must forcibly use one American to serve another American. Forcibly using one person to serve another is one way to describe slavery. [bold added]
