Instead of taxing the rich (good luck) or trying to raise minimum wage, we just create a currency, all agree to use it, and give a UBI in that currency. Boom. New system. We don't even use their money at all anymore.
Most of the jobs that people "work" are fake. No one needs them to exist at all; they benefit no one. We just have all these useless jobs because that's how they ran the system for 100 years. Just think how much less cringe our world would be. People wouldn't be so desperate for survival that they take advantage of other humans, work cringe MLM jobs, try desperately to create a career as influencers... no more real estate agents, sitting in an office for eight hours doing nothing for something that doesn't need to be done. Drastically reduced waste. Would people be pumping out bunk clothing brands if they didn't have to find a way to make money? How many less completely useless items would be created?
A money system by the people for the people. And we just stop. Doing all the bullshit that no one needs done.
