Firstly, I don’t care about your serious perception because you decided that you could calmly rewrite my ego, naively believing that I would agree.
Secondly, the popularity of an idea in science does not come from the thermogenic concept of popularity itself) but from what actually complies and corresponds to reality to that extent. Marx is not used because he is essentially false in his understanding of capital.
Thirdly, I will not write about the critic of Marx (specifically my ok?), because in essence such esoteric knowledge does not deserve you. But if you are interested, read economists like Bawerk (as I already said) or Mises idk.
