What if we were stuck on a spaceship with 100 other humans? There’s a lot to maintain on a spaceship to keep it operating so we all don’t die.
What if there was a contingent of 10 people on this ship who refused to help with the operations of the ship? They decide to hole up in the cargo bay, doing nothing but feeding their own desires from the replicators.
90 other people bust their balls to keep the ship running - long hours, deferring pleasure until the work is done, earning everything they work for.
Now multiply the size of that ship by 70,000,000 and you have Earth.
