IIRC, Bezos used to sell $1Bn worth of Amazon stock every year to fund Blue Origin, not sure what the funding format is now.<p>Blue Origin is proof that just throwing money at a problem does not achieve results, and saying the Musk's only contribution to SpaceX to was "using his money to buy success" is a fallacy.<p>I don't how much you can look into his "engineering" prowess.. but clearly it was more than zero.
