No individual has had a greater influence on economic policy than Adam Smith. Smith laid the foundations of classical free market theory and most notably conceptualized the idea that profit maximizing firms interacting with rational consumers in competitive markets lead to prosperous societies.  For this reason, Smith is frequently celebrated by free market fundamentalists as a champion of Laissez-faire capitalism.
However, despite what his contemporary followers claim, Smith recognized the limitations of the market and the necessity of government:
“According to the system of natural liberty, the sovereign has only three duties to attend to; three duties of great importance, indeed, but plain and intelligible to common understandings: first, the duty of protecting the society from violence and invasion of other independent societies; secondly, the duty of protecting, as far as possible, every member of the society from the injustice or oppression of every other member of it, or the duty of establishing an exact administration of justice; and, thirdly, the duty of erecting and maintaining certain public works and certain public institutions which it can never be for the interest of any individual, or small number of individuals, to erect and maintain; because the profit could never repay the expense to any individual or small number of individuals, though it may frequently do much more than repay it to a great society.”- Adam Smith IV.9.51
Smith believed that it was essential for government to provide certain goods like infrastructure, banking and education because they provided the foundation in which markets could flourish. Nevertheless, Smith recognized the danger of government when their authority was used only to benefit a small number of individuals. Indeed, Smith warned again and again of the collusive nature of business interests, the formation of cabals or monopolies, and the political power this gives to the richest members of society:
“It is in the age of shepherds, in the second period of society, that the inequality of fortune first begins to take place, and introduces among men a degree of authority and subordination which could not possibly exist before. It thereby introduces some degree of that civil government which is indispensably necessary for its own preservation: and it seems to do this naturally, and even independent of the consideration of that necessity. The consideration of that necessity comes no doubt afterwards to contribute very much to maintain and secure that authority and subordination. The rich, in particular, are necessarily interested to support that order of things which can alone secure them in the possession of their own advantages. Men of inferior wealth combine to defend those of superior wealth in the possession of their property, in order that men of superior wealth may combine to defend them in the possession of theirs. All the inferior shepherds and herdsmen feel that the security of their own herds and flocks depends upon the security of those of the great shepherd or herdsman; that the maintenance of their lesser authority depends upon that of his greater authority, and that upon their subordination to him depends his power of keeping their inferiors in subordination to them. They constitute a sort of little nobility, who feel themselves interested to defend the property and to support the authority of their own little sovereign in order that he may be able to defend their property and to support their authority. Civil government, so far as it is instituted for the security of property, is in reality instituted for the defense of the rich against the poor, or of those who have some property against those who have none at all.” – Adam Smith V.1.55
What Smith is describing here is the foundation of corporatism. Simply put, corporatism is the control of the state by the richest interest groups. In practice, corporations will lobby the government for things like subsidies and profit reducing regulations. Free market fundamentalists will often call this level of conspiracy “crony capitalism.” They argue that by simply reducing government size that the “free market” will naturally resolve this issue. This, however, is a misguided fantasy with no factual basis in history.
Before we go any further we must identify what a “free market” actually is, or at the very least, try to understand what it implies. Let’s look at some modern dictionary definitions:
“An economic market or system in which prices are based on competition among private businesses and not controlled by a government.” – Merriam Webster
“Business governed by the laws of supply and demand, not restrained by government interference, regulation or subsidy.” – Investor Words
Today, the term “free market” is often defined as a market without government regulation. Implicit in this definition is that buyers and sellers would have “prices based on competition”, markets would follow the “laws of supply and demand”, and economic activity would be “unrestricted.” Immediately we can see contradictions in this concept.
The following excerpt from Understanding Capitalism demonstrates this quite concisely:
“Without government interference there is nothing to prevent interference, restriction, and subsidy by the mafia, an activity for which we have real world examples. Without government interference there is nothing to prevent the erection of barriers to free transaction, used either to extract rents, to marginalize competition, or to punish groups of people based on any number of criteria such as race, religion, gender, etc. Furthermore, there are any number of ways in which non-governmental entities can implement rules and regulations which distort the laws of supply and demand, a classic example being the National Football League’s imposition of salary caps and profit sharing across organizations.” – R.G. Price, Understanding Capitalism
So here we have a paradox. Without the government imposing rules on the market, there is nothing to stop the “free market” from restricting itself from the next powerful authority. There are countless examples of the “free market” distorting itself. To name a few:
Coca Cola paying retailers to eliminate competition
In each of these cases we see private actors take action to subvert the “laws of supply and demand,” distort “prices based on competition” or prevent people from transacting freely in an “unrestricted” market without any coercion from government forces. Indeed, it was the implementation of government regulation that ultimately led to a freer market in these cases.
To conclude, Smiths analysis of free markets provides a solid foundation for creating a prosperous society. However, free markets ≠ no government regulation. A freed market must have limited, but smart regulations towards the highest concentrations of capital. It must also account for externalities. And ideally, the freed market would be one that redistributes its capital to all its citizens, but I’ll save those thoughts for another time.
