Corporatism is classifying society into different interest groups according to their social and economic interests. Although it has been associated with many ideologies it is most commonly linked to fascism, which states an authoritarian government is needed to coordinate all these different factions. Basically I am rejecting the all too common conflation of conservatism with fascism made by politically uninformed people.
I am also addressing the common association of conservatism and Big Business (i.e. corporate) interests. It doesn’t necessarily have to be that way. The primary advantage of capitalism over socialism is that a state monopoly has no incentive to provide goods at a low price whereas a free market with multiple actors involves economic competition and thus creates incentives for economic actors to offer low prices to undersell rival firms. The more economic actors there are, the more competition there is and the better it is for the consumer. Thus a capitalist system dominated by many small businesses is actually more efficient than an oligopoly of a few large firms. Essentially a forward-thinking conservative will support small businesses over large corporations on this principle and try to remove government regulation that strangles small businesses to preserve the interests of corporate lobbyists.
