Even if the are more efficient, they earned the regarding profit for a small number of people, who has to much. For the society it is a loose loose. The services become more expensive and it lead to a redistribution of wealth from poor to rich, whitch is even worse for the society and the economy.
Look at spacex they are more efficient then nasa
What do you base that on?
Spacex has had zero successful missions to Mars. NASA has landed 5 rovers.
Well one metric would be cost per kg to get something into space. I also recall a lot of people dying when NASA first started going into space, of which SpaceX has not had any rockets explode with people in them, but I'm not impaired enough to make that false equivalence like you did with Mars.
Of course my comment is false equivalence, because the initial assertion is false equivalence.
You can't compare NASA and Spacex because they have different goals. NASA even contract many of their payloads to Spacex, which they wouldn't do if they were in the same business.
there's an exception to the rule
