More on Adam Smith, this time from the pen of Michael Hudson in his excellent heterodox ‘dictionary’ J is for Junk Economics (p.28):
“Adam Smith (1723-1790): Traveling to France and meeting with the Physiocrats, Smith adopted their advocacy of a land tax: “Landlords love to reap where they have not sown, and demand a rent for its (the land’s) natural produce” (Wealth of Nations, Book I, Ch. 6, S.8). Landownership privileges “are founded on the most absurd of all suppositions, the supposition that every successive generation of men has not an equal right to the earth…but that the property of the present generation should be…regulated according to the fancy of those who died…five hundred years ago,” that is, the Norman conquerors (Book III, Ch. 2, S.6). Driving home the point, he adds: “The dearness of house-rent in London arises…above all the dearness of ground-rent, every landlord acting the part of a monopolist” (Ch. 10, S.55). Yet free market economists have tried to appropriate Adam Smith as their mascot, stripping away his critique of ground-rent and monopolies to depict him as a patron saint of deregulation and lower property taxes.
Regarding monopolies, Smith observed that almost every private interest represents its gains as a public benefit, as when CEO Charles Wilson proclaimed that what’s good for General Motors is good for the country. But in reality, Smith noted: “People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices…though the law cannot hinder people of the same trade from sometimes assembling together, it ought to do nothing to facilitate such assemblies; much less to render them necessary” (Book I, Ch. 10, S.82).
Opposing the wars resulting from empire building and colonialism, Smith urged that the American colonies be liberated so as to free Britain from the costs of wars financed by public debts that taxed consumer essentials to carry the interest charges.”

“People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices…though the law cannot hinder people of the same trade from sometimes assembling together, it ought to do nothing to facilitate such assemblies; much less to render them necessary” (Book I, Ch. 10, S.82).
I suppose, this would have made Adam Smith, who certainly was a broad-minded thinker and no doctrinaire, an opponent of the EU.
“The viciously anti-democratic nature of the EU is quite easy to explain: (1) the European Commission, despite being unelected, is the executive of the EU and has the sole right to propose legislation. This European Commission proposes and formulates legislation largely in secret with committees filled with big businesses and corporate interests …”
