There are no objective ethics. It's an open problem.
There's a whole lot of words to be said about that, but it's hardly worth discussion because ultimately the result would be wasted breath.
Anyway, the sphere of economics is the least ethical domain of humanity there is. My dollar is not equal to your dollar, and our dollars aren't equal to Musk or Bezos. We pretend that is the case. There never were and never will be equivocality in exchange unless it's one idea for another.
