If you follow the flowchart and dive into most economics departments you will encounter what I'm talking about.

What are you talking about Keynesian liberals or something? I do like to read Adam Tooze to see him close in on an interesting point only to veer wildly. Foreign Policy in general has some interesting writers if you want to mine the most advanced liberal cope.

The model of economics I'm describing is the one which has been most heavily promoted by the west, neoliberalism, it has been used to dissolve the social welfare state which was set up to compete with the socialist bloc since defeating its chief rival and counterbalance in the USSR. It's an ideological persuasion that works along with coercion and subterfuge to eliminate capital controls and suppress the masses with starvation and crackdowns, especially in peripheral countries which are starting to establish socialistic policies or nationalize natural resources. Look at Chile for a perfect example of liberal economics in practice.

I am aware of plenty of different non-Marxist models of economics and none of them are great because they treat various sectors of production wrong. China and Vietnam have their shit all figured out that's why finance capital and food aid can't decimate their agricultural production and then extort them into unfavorable IMF deals.
