Keynes merged economics into politics and politicians abused it unfortunatly economics does not rule politics I do not believe anything Keynes wrote about can be considered liberal period He may of thought that but I think you should ask von Mises Hayek and Friedman about that They would tell you that what Keynes wrote about smacked liberalism in the face The only reason Keynes can be considered liberal is because populists politicians and the media have conflated them together ignorance or practicality I m not deciding But government interventions effecting supply and demand prices etc are not liberal economic policies Thus not classical liberal and get it straight Keynes diverged from liberalism
