I wish more intellectuals had their "brain on capitalism".

It is dismaying to find out how many American academicians take Marxism seriously - unless they stem from countries like Cuba that had the misfortune to actually let Marxist ideas rule them. It is mental fentanyl for certain kind of collectivist mind.

Give me Hayek and Buckley instead.

Which ideas constitute Marxism?

In theory? The most obvious is labor theory of value, plus false consciousness and the division of the society into exploitative class and exploited class.

In practice? For example, nationalization of businesses and collectivization in rural areas, including suppression of "kulaks".

It's possible to criticize one thing without endorsing another. Your comment reads like a response to someone criticizing what the current US administration is doing by saying "yeah but the Democrats..."

Binary thinking is analogous to quantizing an LLM to 2 bits (worse, actually). You're not going to get good results.

Most countries that tried experimenting with various systems settled on a combination of a relatively free market with a welfare system supported by taxation of the resulting economic surplus. Which indicates that this is what the population at large finds most acceptable.
