P.-J. Proudhon, System of Economical Contradictions…
“ Therefore the progressive tax stops the creation of capital; furthermore it hinders its circulation. Whoever, in fact, should want to buy a plant for any enterprise or a piece of land for cultivation would have to consider, under the system of progressive taxation, not the real value of such plant or land, but rather the tax which it would bring upon him; so that, if the real income were four per cent., and, by the effect of the tax or the condition of the buyer, must go down to three, the purchase could not be effected. ”
