Keynes merged economics into politics and politicians abused itunfortunatly 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 togetherignorance or practicality Im 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
