The medical licensing body is making the market in surgeons. Their interest is in keeping wages high and supply low. In fact, “making the market” is not even the right analogy - the licensing body is the sole supplier of surgeons.

Nobody is making the market in game devs, so market wages prevail. Gaming happens to be the world’s most popular form of entertainment so it’s not surprising that more people want to be game devs than say write ERP software.

There are also way fewer game dev jobs than there are general dev jobs. This isn’t rocket science.
