Really, you don't see what is happening here?
Who else mounted a private space company able to dock with that of the global governmental effort that is the ISS?
But. They're not there yet. At the moment, they're currently providing a launch facility that is equivalent to services offered by a number of other vendors, albeit at a slightly lower (currently) price. And the service they're providing really does not directly impact on 99.9% of the lives going on around you.
Yes, their reusable launch system program is way ahead of anything else anyone is doing, but it's still experimental, and isn't yet providing benefits to even their direct customers, let alone anyone else.
Musk hasn't made lasting change yet with SpaceX. I really, really hope he does. Becoming a multiplanetry species would be the biggest thing for Humanity since, well, fire, standing upright, or speech, and Musk seems to be the person best placed to make that happen in the next 20-40-odd years.
But he's not done it yet.

There are plenty of ruthless people in business even today. But Rockefeller was driven by the belief that cooperation in business, rather than competition, was the way forward for society. The business he built reflected that. Eventually the world learned from his model and now business isn't quite so cutthroat.
But it took Rockefeller to create this new order. Someone so genius at business that there was no stopping him from doing anything he wanted to do. Not even the full might of the federal government could bring him low. Maybe they could have eventually, but the government's position on monopoly softened after it realized what the economies of scale it generated meant for our wartime industrial efficiency. There were other titans in that time period. Rockefeller stands above them all.
