How do you evaluate the current left-wing trend of disdain for mainstream modern economics?

The key point is this sentence: ?However, in Marxist political economics, mainstream economics is also used for research, such as Romer’s rational choice Marxism. The neoclassical model can also defend socialism. . We note that in the first clause, Ma Zhengjing is the subject of environment and generation, and mainstream economics is the object and object. That is, Ma Zhengjing uses mainstream economics to do research. It is clear from the position of the predicate ("use") . But in the next two sentences, mainstream economics is the subject and environment, while Ma Zhengjing becomes the object - Romer (a "mainstream economist") used Ma Zhengjing for research in the book, neoclassical The Marxist model (a subset of mainstream economics) is compatible with socialism (a subset of Marxism).

This error is so obvious that it is difficult to read clearly at a glance. Unlike many people who criticize An Ling, I think An Ling is low-level and boastful. On the contrary, I have high regard for An Ling's level. At least it is impossible for her to write such an obviously sick sentence without knowing it. So I think she must not be stupid, she must be bad. This is a rhetoric. The first sentence implies that Lao Ma Laoen's Ma Zhengjing (who you respect, admire, study and study) is also studying mainstream economics. The second two sentences supplement the content of "mainstream economics" and imply that the neoclassical model should be adopted. . This method of breaking down the original connection sequence of events or language elements and only hinting at the content is also very common in literature that uses metaphorical techniques. For example, the three fairy tales of Yun Tianming in "Three Body III" are very typical. , another example is Jiang Wen's "Let the Bullets Fly." However, even without such grammatical analysis, it is already a joke in itself for a person to return to "modern mainstream economics" with the intention of "returning to Marx."
