The financial elite gets the mercantile middle classes hit the hardest by their bell curve tax system to rally for their own tax exemptions and deregulation also making these ideologies easy to spread in bourgeois or even petite bourgeois society while they'll never really reap the benefits.

Also reading the history about the advent and transformation of neoclassical economics it seems it was exactly that, a well thought out scheme to dupe the middle and lower classes to accept a system never really intended to favour them.

Classical liberalism seems almost left wing in this context, and that is not weird when realising this was a project thought by a nexus of plutocrats like Rockefeller in combination with the dawning sciences of propaganda and control of the dangerous masses that could become enamoured with socialism.

A new ideology had to be spread and so the intelligentsia of the day met up very openly to discuss rebranding various older unnamable ideologies for the masses to steer them from collective power or true autonomy.

It sounds very conspiratorial like this if it wasn't right there in history in the culture around Edward Bernais, american oligarchs or italian fascists talking about the need for "A new liberalism" in the 1920's and masses that could be "moulded" with ideology or phantasms created top down.
