Adam Smith the father of modern capitalism was a huge propopent of a progressiv
Moreover, in this passage Smith goes on to specify progressive, not flat, taxation:
"The rich should contribute to the public expense, not only in proportion to their revenue, but something more than in that proportion"Smith even specifically named taxes that he thought should be required by the state among them luxury goods taxes and tax on rent. He believed that tax laws should be as transparent as possible and that each individual should pay a "certain amount, and not arbitrary," in addition to paying this tax at the time "most likely to be convenient for the contributor to pay it". Smith goes on to state that:
"Every tax, however, is, to the person who pays it, a badge, not of slavery, but of liberty."Additionally, Smith outlined the proper expenses of the government in The Wealth of Nations, Book V, Ch. I. Included in his requirements of a government is to enforce contracts and provide justice system, grant patents and copy rights, provide public goods such as infrastructure, provide national defense and regulate banking. It was the role of the government to provide goods "of such a nature that the profit could never repay the expense to any individual" such as roads, bridges, canals, and harbours. He also encouraged invention and new ideas through his patent enforcement and support of infant industry monopolies. he supported public education and religious institutions as providing general benefit to the society. Finally he outlined how the government should support the dignity of the monarch or chief magistrate, such that they are equal or above the public in fashion. He even states that monarchs should be provided for in a greater fashion than magistrates of a republic because "we naturally expect more splendor in the court of a king than in the mansion-house of a doge." In addition, he was in favor of retaliatory tariffs and believed that they would eventually bring down the price of goods.
As you can see todays Republicans are way out of line with the ideas of father of modern capitalism.
They just seem to make it up as they go along. Their real aim is not to make America great again but to destroy a President and the people who voted for him.
