This collective outcry by the left over Elon Musk becoming a trillionaire, which is misleading in the first place because virtually all of that wealth is tied up in stocks rather than sitting in a bank account, is another reminder, not that we needed one, that among those on the left who genuinely believe what they are saying, economic illiteracy is rampant.
Their entire worldview is framed by the zero sum game. If someone has a bigger piece of the pie, then someone else must have lost some pie. They simply cannot grasp the concept that Elon Musk singlehandedly made the pie a whole lot bigger for millions and millions of people. It just doesn't compute for them.
This also happens to be a damning indictment of the schools, universities, and media institutions the left dominates.
