Others are big kids who can't wait to get into the lab for another rewarding day of exquisite, exploratory fun. Still others care very deeply about the value and meaning of science. I've never heard anyone call science communism. It has absolutely nothing to do with communism. In fact, communists don't like scientists very much.
Scientists are too hard to control.
They care too much about truth. University scientists aren't the only people doing research, of course. For-profit corporations engage in research and development. But the consequences illustrate precisely whats at stake. Proprietary knowledge doesn't get disseminated unless doing so enhances the corporation's bottom line.
