Alternatives exist. One alternative is Distributism, the economic state where the possession of land and capital, instead of being concentrated in the hands of a few, are maximally distributed among all men throughout society -- a system of communitarian free-enterprise economics based upon the medieval Christian social order that relies on widely-distributed capital and guild regulation of commerce as the basis of economy. Distributism was championed by G.K. Chesterton, Hilaire Belloc, and many others, and its principles were affirmed by His Holiness Pope Leo XIII in his famous 1891 encyclical Rerum novarum.
Unfettered capitalism leads to the same place unfettered communism leads: a condition of widespread misery, tyranny, and injury to the dignity of human life. Those seeking an economic alternative with a human and Christian character should explore Distributism.
