The question is who decides what is adequately compensated. The (almost) free market or some bureaucrat who has their fingers in the till?
Take the inventor of the laser. Think about it. If you came up with a great idea that could make you millions, would you like someone else telling you how much you can get? It works that way in other economic systems.
So SawStop has an innovative table saw. Pretty good one, but other companies are looking at their long history and applying innovation to their tools. Prestige brands like Powermatic had better get their act together as we won't want 50 year old designs much longer. Even Delta put the tilt crank on the front FINALLY! Too bad their quality is so poor, I would have bought one for that feature. Harvey is rethinking the fence. DVR power coming to tools. So, as their patents eventually run out, they need to come up with the next big idea or be reduced to just another imported race to the bottom price brand. As Getty told us, reproducing ideas is hard.
