No, obviously not. Ramping up his car company from roughly nothing to major global presence, kickstarting the world on electric traffic, and setting up private space rocketeering on the side. Oh, and becoming the supposedly richest person on the planet in the process. How insufferably childish of him.
As far as I remember it's: being born rich, getting lucky on one investment and than chewing up ideas of other people and having them sweat his bullshit out to keep their jobs sounds more like the true history here. Didn't get much better in the recent years.
I mean Trump made it to the president of the US of A and I wouldn't consider him an adult person either. History looks pretty similar. Just a different time with the appropriate difference in methods.
Sums it up in the best possible way.
