The classical economists that Hudson mentions here

my  book describes the "intellectual engineering" that has turned the economics discipline into a public relations exercise for the rentier classes criticized by the classical economists: landlords, bankers and monopolists. It was largely to counter criticisms of their unearned income and wealth, after all, that the post-classical reaction aimed to limit the conceptual "toolbox" of economists to become so unrealistic, narrow-minded and self-serving to the status quo.

called their discipline political economy. I think one of the latest to do so was John Stuart Mill, who wrote in the middle third of the 19th century. Unfortunately, institutional economists and other who study the power relations that Hudson also mentions as central to economic reality are labelled as "sociologists" and ignored by mainstream economics.

It turns out that Economics is Politics after all.
