Where in the rest of the developed world are you thinking is socialist? I would say that, in the developed world, very few countries go further left than being social democrats, like the Scandinavian countries. These countries are explicitly not socialist.
I notice you conveniently left out anything about SpaceX, where he’s already dramatically cut launch costs, and has hardly even started taking advantage of the reusable rockets he pioneered. He’s just getting started, and is already solidly one of the best three people in history to date at building rockets. He’s got plenty of time left to solidify that as number one. Government projects have had numerous chances, in both capitalist and socialist systems, to accomplish what he has, and they haven’t.
As for Tesla, it might still succeed, though things don’t look great right now, but nobody succeeds every time they try something.
Edited because I just saw this:
FFS. You pretty clearly don’t have the faintest idea what you’re talking about here. NASA hasn’t even had a launch vehicle since the shuttle was retired, and SpaceX cost per KG per orbit is already ~15x less than the shuttle (using the most charitable estimate of the shuttle cost), for a non-reusable launch. That is set to come down a lot further as soon as they start selling reused rocket launches routinely.
