All three of Musk's most recent ventures (SolarCity, Tesla, and SpaceX), depend either on direct or indirect government subsidies. It's not just that Musk is a workaholic, or possibly innovative, but his ability to "work" the system that sets him apart. US tax payers are paying a significant portion of the bills for his ventures. Since I agree with his goals, it doesn't personally bother me very much but it still is something worth thinking about.
US Tax payers will be paying for something, considering that the majority of the US economy is private, and the government has to get stuffs done somehow. So if you agree with the goals of a private entity that the government is spending the money on, it's about as good as it could be.
