You're confusing SpaceX and Tesla.

Maybe you should review these pages and get your facts straight:

So what if he did? What were they doing before he got involved?

If it was so easy to bring this kind of stuff to market then why aren't more people as wildly successful? This kind of "Musk didn't do do anything or have the vision" hate is beyond tiring.

There are plenty wildly successful people. There's a list of billionaires, and even more millionaires. Of course, these people tend to pull up ladders behind them, so they prevent other people from their opportunities. :)
