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.
UBI has been tried experimentally around the world many places including the US and did not have that effect "the money people had received was not squandered on frivolous products such as drugs and luxury goods": https://en.wikipedia.org/wiki/Universal_basic_income_pilots
Which experiments were successful depends on what your desired outcomes were, but none were as bad a you suggest, I would say many succeeded.
I do not know how COVID support worked in the US, but one of the things you refer to seems to be loans to businesses, which is very different from UBI. Were people given a fixed and guaranteed income stream not linked to earnings during COVID?
My impression is that China has a pretty high standard of living. They have been extremely successful in reducing poverty over the last few decades. You should see how shiny even some of the third tier cities are.
I wouldn't use the COVID economy to understand anything except "What happens to an economy during a pandemic?" People had more money, but there was a lot less to spend on for a while. Not to mention the psychological effects of lockdowns, restrictions, or quarantining.
The fundamental problem is that power and resources are always captured by Cluster B types, and Cluster B types are poison to every form of social organisation.
So it's true it almost doesn't matter, because you can absolutely guarantee you're going to have growing inequality, political instability, and a culture of dishonesty, abuse, and contempt, unless you keep Cluster B types far, far away from resource dominance, strategy, and enforcement.
I don’t think that power and resources are always captured by Cluster B types, and that statement is doing a lot of load-bearing in your argument. You’re going to need to back it up somehow.
> it is fundamentally important that nobody has too much power
> taking power away from the capitalist class
An obvious and apparently irresolvable contradiction.
Capitalist power is inherently anarchic and isn't power at all. It's simply order emerging from the anarchy of the market. But the ability to take that power away from them, no matter how you measure it, itself falls into the category of "too much power" with wide margin. And with this amount of power there will be no change of hands that hold it.
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.
