I'm a graduate student in theoretical physics. Do you really think I can't understand an economics book that uses first year analysis and topology?
In real fields of study, we can at least agree on the foundations of the field and some basic results. What the fuck do mainstream economists agree on? For any given policy point, if you ask two different economists, you will get two different answers depending on who is paying them to find the answer, or what their ideology is. Minimum wages, income inequality, taxation, IP rights, I have seen papers coming to opposite conclusions about what is to be done on these issues.
The only things I've seen economists almost uniformly agree on are:
We all saw how that went.
And yet in this very year research has come out documenting the negative effects of a sudden shock in regions heavily exposed to Chinese manufacturing. It is thanks to these very regions that we now have President Donald J. Trump.
And yet in this very year research has shown what should be trivially obvious, that the "gains" in globalization largely have gone to the bourgeoisie and China to a lesser extent, mostly at the expense of workers in rich countries. I am sure you have seen the elephant graph of global inequality by now if you are an economist. It is thanks to this that we now have President Donald J. Trump.
Most economists think immigration is a net good for the economy, and yet in this very year I have read research pointing out that third world immigrants essentially compete with workers in rich countries without highschool degrees, driving down their wages. Another example of a transfer program to the bourgeoisie, who would have thought? This is another reason why we now have President Donald J. Trump.
Macroeconomic models are also complete garbage that have no predictive power. If they can't predict and prevent crises, what is the fucking point?
Given all this, why the fuck should I take modern economics seriously as a "science" or even a social science? All they can seem to agree on is that policies that benefit the bourgeoisie are good, especially when third-worlders get a few table scraps so that critiques said policies can be dismissed as racist? Psychology is currently imploding due to a replication crisis. Political Science should be dead and buried after this election. I am sure that modern economics will be next.
How does this compare to calculating the fine structure constant to one part in a trillion, modern computers, evolutionary biology, modern medicine, and so on? It is a fucking joke of a field.
