Quantum mechanics only says that you can’t predict the spin of certain particles. Those particles are at a vastly different scale of the things we see in everyday life. Yes, a photon might suddenly change direction and I won’t see it because it’s a wave function, right? But only at a really small odd. I bet it has never happened to me or anyone in my continent, if not the entire human race in all time. Let alone neurones in my brains experiencing quantum effects.
Quantum mechanics dismisses no argument of determinism because how low the possibilities are.
Even if macroscopic particles do behave randomly, it is still a random behaviour, not your decision.
And no. A person who pays millions dollars of tax does not have a louder voice than I do. We are all the same tax payers who pay proportionally to our earnings.
Give me back the public infrastructure I need and the billionaires hate.
