proprietary tool
Surprise, surprise.
Government intervention that causes a problem that can only be solved with... yet more government intervention.
Prove this statement. Prove that government intervention is why proprietary tools exist.
Before you launch off onto an anti-patent speech, I'll remind you that patents have nothing to do with it because proprietary tools exist whether there are patents or not. The simple fact of the matter is that when manufacturers make obscure parts of products require a special tool, there just isn't enough of a demand for the tool to warrant a separate company investing the money, time, and effort to sell a half-handful of the special tool. How often does Joe Public need the proprietary tool to remove the fan clutch on his M3? Hell, even the dealers don't use it that often. So why is Craftsman going to invest the large amount of dollars necessary and dedicate the floor space for machining a tool that they're going to sell five of a year, if they're lucky?
That's just the free market at work for ya. Government has nothing to do with it.
