There’s a approach and, I recommend, just one approach to defend populism from a liberal viewpoint: it’s to reject the populist idea of “the folks.”
Let the folks be plural, that’s, a set of people. Let every particular person be acknowledged as having a proper to veto (at some contractual-constitutional stage) any prohibition or mandate he (or she, in fact) doesn’t consent to. A fortiori, no subset of the folks could use coercion in opposition to the people in one other subset. It follows that the elite or the specialists (“they”) or the politicians themselves could not legitimately boss folks round. If populism is thus characterised, it’s defendable from each an ethical and an financial viewpoint as it might coincide with (classical) liberalism. Liberalism is a couple of damaging veto proper of every particular person–a minimum of as formalized by James Buchanan and Anthony de Jasay, however the paradigm runs deeper. Liberalism actually and emphatically doesn’t help an unrestricted optimistic proper of some people, even a majority of them, to impose bans or mandates on people within the plural folks.
That’s not how populism, in the usual which means of the phrase, is outlined and bought to the lots, that’s, to a majority or a plurality of them. Populism requires the existence of “the folks” singular (see, for instance, Cass Mudde and Cristóbal Rovira Kaltwasser, Populism: A Very Brief Introduction [Oxford University Press, 2017] for the academically accepted definition, which is near the one I assign to the populists). If “the folks” (singular) doesn’t exist as such, then populism is just not doable; it’s only a label that hides an interventionist, collectivist, and authoritarian ideology. (See my “The Impossibility of Populism,” The Unbiased Assessment, Summer season 2021.)
To be each internally constant and suitable with liberalism, populism must take “the folks” within the plural and liberal sense of “people,” with none extra deserving of energy over his fellows. It will not be “populism” anymore.
