my understanding is that reagan was ideologically in line with thatcherism and it's elevation of liberal concepts of free trade over the traditionally mercantilist views of british conservatism, but that he would often use tariffs against economies where there was overwhelming government intervention. that said, reagan's massive defense spending as a form of economic stimulus, and the eye-boggling amount of debt he created via defense spending, was also extremely keynesian. reagan was more like the last tax and spend liberal in american history than the first thatcherite neo-liberal.

i don't regard ronald reagan as much more than a dumb cowboy that destroyed america, but i likewise don't think reagan would have much respect for donald trump, or that they have much in common, policy-wise.

trump is more like the love child of bill clinton and richard nixon mating.
