Awesome work by spacex. They are peerless, except if you want to count massive superpower governments as peers.
If you wonder why all of the shareholders of Apple aren't plowing their money into spaceflight, well it's probably because they're a retirement fund, or just aren't rich.
Other people invest in making this world a better place, see Bill Gates, or other worthwhile causes, of which spaceflight is just one.
Not everyone can be Elon Musk, nor should they try. There is much to do with our feet on the ground.
Less snarkily, the pitch of Elon Musk is surprisingly selfish--he's basically doing this as much so he can get to Mars as anyone can. By contrast, people like Rockefeller and Carnegie in the past are largely responsible for endowing public culture in the form of museums, concert halls, public libraries and the like, and the modern day equivalents like Gates and Buffett are attempting to eradicate malaria from the world.
Nevertheless, you should reserve ire for those who have the ability to do philanthropy and fail to engage in it in any form as opposed to those whose philanthropy isn't in the areas you'd prefer.
"Elon kind of money?"
Heard of government subsidies?

Edit: not taking sides and adding my subjective point to the article; just merely stating fact that Mr. Musk projects are in large part government-funded.
That amount is for Tesla and SolarCity combined. To put things into perspective, GM received a $50B bailout, Ford got almost $6B for “energy-efficient” cars, as did Nissan with $1.6B.
Finally, almost all of those are loans, tax credits and incentives, not money 'out of pocket'. The goal is always to generate more wealth than was “spent”.
