Utter fallacious nonsense. read Bastiat's That which is seen and that which is not seen to help cure your economic ignorance.
IF taxes will continue to be confiscated from my paycheck( AND THEY WILL)and be spent on something, I would rather have it spent on a private defense contractor who will hire 1000 high skilled folks to build an advanced weapon system. These 1000 folks are NOT government employees, with government. They spend the money they make for what they want.
Mid 19th century French economic theory notwithstanding.
