who will redistribute stuff?
You are simply selecting new elites to be from the redistributor class (vanguard party, Nomenklatura, secret police etc), instead of the entrepreneural class.
Works well if you are the one redistributing stuff from "rich to poor", but it ends up as creating a new elite class, every single time
Doesn’t seem like it did it in Norway. Or the Us from the new deal until the 1970s. Or the vast majority of western Europe. This red scare stuff is tiring.
This is a genuine problem indeed and part of the appeal of an UBI. The idea being that if the rules of redistribution are dead simple, then that helps minimize the potential for grift, which in turn minimizes the potential danger of a redistributor class.
That said, it is fundamentally important that nobody has too much power, and that power changes hands on a regular basis.
At a global scale, this necessitates taking power away from the capitalist class.
Ideally that power just doesn't go to anybody, but to the extent that it has to go somewhere, it almost doesn't matter where. Or perhaps it's better to say that there are many options that are acceptable and better than allowing power to continue to accumulate unchecked.
All modern Western-like societies involve some amount of indirect redistribution already. Outside of extremely peculiar places like Singapore or the Gulf states, it's just not seen as desirable or even sensible to have extreme wealth alongside people living in extreme poverty on the equivalent of less than a dollar a day. This actually used to be relatively common in the 19th century, it was the actual kind of widespread pathology that early social reformers railed against.
