Okay, fantastic, now we're getting to the juicy part here. So I agree with you that our markets are heavily skewed with negative externalities and perverse incentives. I also agree with you that these negative externalities and perverse incentives are present in finance and law. I can even agree with you that in terms of the utility functions they ought to serve in an ideal society, it's plausible that they would be commodities rather than this strange realm of both commodity and luxury that they currently occupy. But, I can't agree with you here:
> Finance and law no longer serve to facilitate free enterprise, commerce and national development, but as a means of escaping responsibility and legal jurisdiction.
Finance and law never served to do any of those things. Nor does it necessarily serve purely as a means of escaping responsibility and legal jurisdiction. Finance and law, much like politics, exists to serve empire. In the golden age of expansion of an empire, you see emergent phenomena such as free enterprise, commerce and national development. You may even see people express that such emergent phenomena are the goals of the empire. But I am never convinced by this. The purpose of an empire is furthering its own existence, and once it exhausts the more palatable ways to achieve growth, it turns to less palatable ways.
To reiterate it again, to argue that people would be better off if smart people worked in fields other than finance or law is, in most senses, neither factual or counterfactual, because it doesn't attempt to engage with reality. The reality is that we live in a world that in many ways is not expanding. We live in a world that is increasingly has zero-sum dynamics. When one lives in a world that increasingly has zero-sum dynamics, people start thinking about securing safety and power, which tends to stratify along the caste lines of the professional managerial class, the lines of finance and law.
When you live in an unsafe world, you don't want to try and follow the rules of the game. You want to write the rules of the game. None of this superficial speculation about whether people would be better if more Xs were doing Y actually addresses this root dynamical interaction, or its increasing chaos. And so it would necessarily miss it. That's why I don't think you're wrong. I think you are missing the point.
"Deserve" and "over valued" are not conflated, they are in fact inextricably linked. Market value is aggregated value, and what someone or some profession "deserves" as recompense is also an expression of market value. Of course, our markets are heavily skewed with negative externalities and perverse incentives, which is exactly why finance and law are over valued by any impartial measure of the functions they ought to serve in a free society.
Finance and law no longer serve to facilitate free enterprise, commerce and national development, but as a means of escaping responsibility and legal jurisdiction.
