He didn't build Tesla..he took it over from the actual person who did. (because Musk wasn't getting any spotlight and we know how big his ego for that is)
dude, I am no Musk fanboy, but this is a bald faced lie. YES tesla existed before musk took it over. it had no cars, no production line; all it had to it's name were a couple of patents.
Its was being used as a tax shelter by it's former owner. Musk bought it for a song because he thought a few of the patents were good, and the name was fire. He wasn't buying anything else.
I would say he "built" tesla since there wasn't really a tesla before he purchased it, outside of some paperwork and an office. He didn't FOUND tesla, had you used that word your comment would have closer to the truth.
That said; there are better ways you could have attacked musk's ownership of tesla. for example, it's clear tesla was original built to take advantage of generous tax credits, using government "welfare" to make the company viable. Now this is true. The difference between tesla and most similar type of companies who were taking advantage of those government subsidies is Musk created a self sustaining company for when those government subsidies ran out. In which case you could say his leadership has been a massive success. He successfully built the first major american car company not owned by one of the big 3; that's no small feat. (not that the big 3 really exist anymore, Chrysler is no longer an american company, and GM seems to be heading the same direction). that it was heavily subsidized by the federal government is immaterial, those subsidies weren't available strictly to tesla, but to anyone who wanted to build an alternate fuel vehicle.
I am highly dubious about Musk having any interest in the environment, he just saw an opportunity to take advantage of massive government funding, put together a great team, bought the right company, and made it work.
those out there who like to claim musk is an idiot are welcome to do so, but for a guy who basically spent every penny on spacex and tesla (at the same point in time in his life) he certainly turned both gambles into something. I credit him not with genius, but with a good nose for employees and a better one for investment opportunities (when he doesn't get in his own way)
