Sure there are people that want to farm. But are there people that want to want to deal with sewage? Why do you think plumbers earn more money than other trades?
I want to run a cafe instead of what I’m doing right now. I don’t want to be a waiter of wash dishes or anything like that. I just want to design the menus and decide on how it’s decorated. Is that the job I’ll have in a socialist utopia, or will I have to do a job I don’t want to do? What if there’s already too many cafes, or not enough people that want to be waiters or was dishes? I won’t have to do anything but I’ll still be provided for?
In the end there will always be people doing jobs they don’t particularly want to do. Someone’s gotta unclog the sewage when the elite of the socialist society plug the pipes with the overabundance of shit they spew out.
How about capitalism? How many MBAs does the world need? Marketing consultants? Advertising cosultants? IT consultants? Consultant consultants? There are countless jobs that serve the machine and no other purpose that benefits society. Somebody will do the necessary jobs. There are more incentives than you realize. For instance, what if I want more than my UBI pays me? Plumbing has entered the chat. The only reason you defend this system so hard as the epitome is because nobody has experienced anything else but this. Its scary I know, but there are more ways than one to exist, and every system has its trade-offs. But our social contract between our governments in clearly broken, we are clearly strung along on the whims of shareholders and capital. Say what you will, but I think we can do better than “those people deserve to starve son, they have no jobs.”
