Interesting question but I personaly believe this is a question of philosophical nature. In our society work is often defined by what you do for your salary and thus how much you earn per hour. And there you can look at how much a "billionaire" gets per hour. And then ask your self, can he really work that much? It highlights how absurd our general idea of work and labour has become because there is no way an ordinary person could in their life work so much that they reach the hourly rate of a billionaire. What I am trying to say here is that the "regular" metrics we employ here simply doesn't work on billionairs and thus the idea that they "work" for their fortune or wealth is kinda skewed to begin with.
I think more important is what ever if we think the work of someone like Bezos or Musk is more worth than those of the 300+ Million of citizens out there. And If everyone should actually aspire to follow the footsteps of those billionairs. I believe if everyone actually did that we would be living in a creatively, culturally and technology bancrupt wasteland baren of all the things that actually make societies what they are.
Because at the end of the day you need the millions of janitors, vendors, hospital workers and engineers out there a lot more than the handfull of billionairs like Musk or Bezos. If the current pandemic tought us one thing than that - I hope. Because as nice as Tesla cars, Space rockets and ordering something on Amazon is (even if we assume those people developed it all on their own) when the shit hits the fan you need someone standing next to your bed pushing that tube down your throat so you you can fucking breathe and that it is a really good thing that some people are willing to aspire to do that. And that there are countless of workers in all kinds of positions that make it possible for intensive care nurses to do their job.
In Germany everyone pays taxes the moment they buy something as we have
A value-added tax (VAT), known in some countries as a goods and services tax (GST).
