What happens when the lazy, parasitical grasshoppers who believe they have a right to a free ride, or those who decide they can have as much not being productive as they would have being productive, outnumber the worker ants? Who get's to decide which section of society has to be murdered first, so there's still enough to go around?
Why work hard when you get the same reward for doing nothing? Why bother to invent if there's no personal reward? Why work or try anything at all? If everyone gets the same no matter what - why bother getting out of bed in the morning?
