Do "real world" Keynesians actually exist? Or is this an economic thought only for hip rich college kids, "science nerds", government Igors, and bought off business?
Are you serious? All of economics is dominated by keynes.
Also you just mentioned college kids, science nerds, goverment and business....who else exists
I do however feel that in many cases people look for theories to justify their actions and not the other way around. I think Keynes gave governments an excellent reason to spend as much as they wanted.
