But this is the fundamental error. They want economy to be like physics. But economy same way as the law is about what people do. As such it CANNOT be separated from
values. BTW, the notion of "value" is necessary.
The economical thinkers who deny it, in fact promote particular interests or values hiding them under the cover of "scientific objectivity". The "invisible" hand of English "free" market robbed whole nations blind.
Free market was behind slave and drug trade, behind exterminations (Tasmanians for example) in modern times behind people like Gusinski, Khodorkovsky and Bierezovsky.
We'll just have to agree to disagree, I'm afraid.
There was nothing "free market" about the slave trade since the commodities were stolen to begin with. Nor with the drug trade since the requirement of freely available information is violated.
Your misunderstanding of economics is hard to overcome within a limited time and space. But that is all it is -a misunderstanding. Economics was not created to be like physics and no economists makes such a claim. Initially it was call "moral philosophy" then "political economy" and used logic, and eventually more and more math to spread its concepts and applicability. That can be taken to extremes which is a valid objection. But that approach has also led to valuable insight.
What is your alternative to "rationality", math and logic?
