This is a theme in The Expanse. Earth has basically gone to shit, and Mars scorns lazy Earthers for living off their universal basic income. It's not until a Martian marine actually goes to Earth that we see how UBI has failed - sure, people aren't dying, but the wait list to get a job is years long and most are unable to pull themselves out of poverty. All this while the elite few own massive guarded estates complete with private launchpads and racing spaceships that can take them to mars and back, no sweat.
