Paul Samuelson was the premier goldbrick in the economics profession in the second half of the twentieth century. He appeared to be working hard, but his output was substandard. He got very rich teaching millions of freshmen how to have careers as goldbricks: how to give the illusion of valuable work, but never producing anything that could be applied profitably to the economy. Keynesianism is goldbrick economics.
