If you follow UBI out a few generations, there will be nobody left to tax, which funds it.
The end result is total system collapse or forcing people to work through total government control, which is where all communist systems end up.
UBI creates a slave class. It's just a dressed up and renamed system that's been tried many times before, and failed.
I'm not sure why every new generation thinks they discovered something new.
You fundamentally misunderstand UBI. it does not stop anyone working, and where it has been tried people continue working because they want more than a minimal income. its not a universal high income, its a universal BASIC inome.
