Elon Musk explains why government efficiency matters:

“I mean, North Korea, they're starving. South Korea, it's like amazing. And so in North Korea, you've got 100% government. In South Korea, you've got probably, I don't know, 40% government. It's not zero. And yet you've got a standard of living that is probably 10 times higher in South Korea. At least.

And then East and West Germany, in West Germany, you had, just thinking in terms of cars, I mean, you had BMW, Porsche, Audi, Mercedes. And East Germany, which is a random line on a map, the only car you could get was a Trabant, which is basically a lawnmower with a shell on it. And it was extremely unsafe. There was a 20-year wait. So you put your kid on the list as soon as they're conceived. Even then, only, I think, a quarter of people maybe got this lousy car.

So that's just an interesting example of basically the same people, different operating system.”
