The real reason for withholding taxes is the unwillingness of workers to share their incomes with the government and the consequent difficulties of collection. To overcome this handicap, the government has simply impressed employers into its service as involuntary and unpaid tax collectors. It is a form of conscription. Disregarding the right of privacy, which is an essential of liberty, the government's agents may, under the law, invade the employer's office, demand his accounts, and punish him for any infraction which they believe he has committed; they can impound his property and inflict a penalty for not having collected taxes for the government.
