That's not true at all. Capitalism has many flaws, but your claim is simply false.
I'm guessing you're conflating capitalism with the deeply non-capitalist legal structures that have been erected on top of it in most of the world. One of the most common examples is corporate welfare, which is exactly as capitalist as welfare for private citizens. I'm not trying to attack or defend welfare with this statement, but I am emphasizing that that's not how capitalism works.
I know the punchline is good as it is but i like to point out that it is actually easier to launch billionaries out of the solar system than into the sun
Not if we superglue and then tie them to the seat. And give them no controls on the inside. And just play a loop of “nah, nah, nah, nah. Nah, nah, nah, nah. Hey, hey, hey. Goodbye.” Not even the whole song. Just that part, on infinite loop.
When your ship is going to the Sun, it has to cancel out nearly all of the orbital motion it inherited from Earth. In order to have the ship drop straight down towards the Sun on a one-way collision course, the ship would have to leave Earth’s sphere of influence at a relative velocity of 30 km/s.
But remember, Earth’s gravity will try to pull the ship along with it, so in reality you’d have to depart from Earth at a relative velocity of about 31.6 km/s (70,700 mph). That’s nearly twice as fast as the ship would have to go in order to escape from the Sun.
The parker solar probe cost was about 1.5 billions. A fully manned one way Mars mission would cost about 20 billions going by the cheaper estimate.
The same one way mission going to the sun would be 10k times more expensive.
I think people should reevaluate doing that to billionaires. I just learned that it would take more energy to fire something into the Sun than it would to shoot it out of the Solar System. We could get more done aiming in the other direction.
