I realize this isn't really the place for this discussion but capitalism doesn't know what the word "efficient" means. Is it efficient to have to buy the same thing twice? Is it efficient to only make cheap shitty and yet still overpriced versions of everything for the consuming public, shit that is designed to fail? Is pollution efficient? Is ruining everyone's lives efficient? Pointless jobs? Rich people? These things are efficient the way fucking for virginity is efficient. The way Elon's Twitter has been efficient. The way shitting the bed is efficient. Which is to say, it's really fucking not.
It's broader that that: it's the most efficient way of extracting money from everything else in general.
Hence just how common it is to see large companies getting massive subsidies or having laws written to benefit them (notice, for example, the Disney Corporation rigging the system to extract more value from the broader society by getting the Copyright terms extended ahain and again), none of which is sales or employment related.
Capitalism doesn't limit itself to things of a trading nature (which includes employment, which is basically people selling their work to others) and that's the core of the problem with it: it naturally corrupts anything around it which can help provide not just trade advantages but even force the rest of society to give larger entities "free" money even outside trade (subsidies, bailouts) or forcing into being paid for that which would be naturally free (i.e. copyright, water rights, even land).
Some people think Crony Capitalism is not real Capitalism, but is actually real Capitalism in it's purest form: the best ROI in this game of who makes the most money comes from buying the referees and those who make the rules.
What about space travel? Preclaimer: I'm a physics student.
Before SpaceX and Indian companies, one ESA launch cost like 500 million dollars, which was impossible to achieve for scientists without direct ESA funding. Now, suddenly physicists can launch small satellites with less than a million.
and do you genuinely attribute that to capitalism or is that a necessary process that comes with developing a new technology and the infrastructure and expertise to operate it
do you genuinely not believe that that would have happened anyway
i'm sure it'd be hard to disentangle all the influences and come up with hard numbers for "how much" "capitalism" "contributed" and how much farther along cheap space flight is than it would have been under some nonexistent alternative system for which we have no real world examples, but to suggest space flight would not have gotten any cheaper than its initial price would be a tough position to defend, let's put it that way.
And then let's put it another way. Do you not think that a focused society, one run properly and without corruption (ie not human), could develop space flight faster, safer, and cheaper, than it could do while burdened with a bunch of greedy thieves who spend more of their resources on bribing politicians, lining their own pockets, and lying to the public about their products through the marketing department than they do on actual technological development?
Capitalism's shit, m8. Just one big lie from start to finish with not a redeeming moment in between. It's a vampire and you're its food. Do you care if your food has opinions?
