Stop quoting him out of context on taxation, education, and monopoly.
Not only did Smith not endorse a progressive income tax, he did not endorse any sort of income tax. “Capitation taxes,” he warned, “if it is attempted to proportion them to the fortune or revenue of each contributor, become altogether arbitrary. The state of a man’s fortune varies from day to day, and without an inquisition more intolerable than any tax, and renewed at least once every year, can only be guessed at. His assessment, therefore, must in most cases depend upon the good or bad humour of his assessors, and must, therefore, be altogether arbitrary and uncertain.”
