What does the worker get out of sending something into space? Nothing
Without NASA and similar agencies, we wouldn't have the means to keep an eye on things like climate change and we wouldn't even have several meteorological services (weather prediction, etc). The USSR developed back then the most affordable space program and to this day several agencies (including private ones) rely on russian technology and their space program for both meteorological services and space exploration.
It was that bourgeois sack of shit Gorvachev and Soros (and this is not even a conspiracy from r/the_donald) who helped crash the USSR economy. This is not even a tankie apology to the soviet union (I'm neither a tankie, nor an apologist); this is merely pointing out facts.
This, is why Private Space is the future
They are not even willing to fix climate ghange, much less terraform/colonize another planet for the benefit of the proletariat. Why would they give a shit about space exploration?
Also, space X is a fraud. They actually tried to create a martian base in order to create a shitty reality show that nobody but faggy tumblr kids gives a fuck about. Elon Musk is a massive cocksucking faggot and he's in bed with wall street and goldman sachs. Quite far from being "private sector", don't you think?
Tl;dr: Of all the government programs, NASA is by far the most benefical, second only to public schools. Under socialism, be it "state" socialism or anarcho-communism, we'd continue to maintain a public space program, for the benefit of the working class and humanity, not for the bourgeois scumbags.
If you wanna complain about wasteful government spending, perhaps you'd like to adress corporate welfare/subsidies and endless military spending, because they take by far the biggest chunk of annual public spending.
Now drop off your LARPing already, "an"cap. This isn't the board for you.
