For instance, I may discover a manufacturing machine that cuts the cost of building semiconductor chips in half. My options under this model, though, are to either price it low enough that I can actually afford to build up a business on top of it (in which case a bigger company can swoop in, buy the rights from me, and destroy my business) or price it high enough that the incumbents can't afford to buy me off (in which case, the proposed tax will be large enough that it'll stifle my business, and the incumbents can just wait until my business dies on its own.)
The current system is far from perfect, but it does favor upstarts and entrepreneurs' ability to build business rather than incumbents. The big thing I'd love to see is a shortening of the patent exclusivity period before becoming public domain.
