I have a BS in physics that I never used, I chose it because I had no idea what I was doing and discovered afterward that most jobs involving physics are less “figuring out how stars work, for the joy of discovery” and more, “figuring out new and exciting ways to kill brown people, for profit,” which I did not sign up for. So, I’ve wound up doing grunt work at warehouses instead. “Learn to wash your own vegetables and you won’t have to pay court to kings,” as the story goes.
A lot of people go into STEM because they just want to solve problems and the issue with that is that if you just solve any problem that’s put in front of you without regard for who’s problem it is and whether solving it will actually make the world a better place, then you belong in the same category as the guy who developed the Blitzkrieg doctrine, who claimed afterwards that he didn’t really care about “politics” and was just doing his job as best as he could. Just because you’re capable of solving a problem and someone’s asking you to doesn’t mean that you actually should.
Imo classical economists were generally more clear-sighted and honest than modern ones. Of course they had their biases and perspective based on their class (and their audience), but at that point economics was so poorly understood that theorists were legitimately trying to figure stuff out, moreso than trying to produce propaganda. Of course, the industrial proletariat and threat of socialism wasn’t really present yet either, so the class conflict was more about new money bourgeois vs old money aristocrats and landlords.
Marx and Smith are a lot more similar than most people think, because Marx was writing in the context of various economic assumptions that come from Smith, such as the labor theory of value, which is usually attributed to Marx but actually comes from Smith.
The thing about Smith though is that his writing style was very dry and repetitive so nobody actually reads him, at best, they might read abridged versions which cut out any inconvenient parts like that. So he just kinda became known as the capitalism guy and is thrown in the same category as Ayn Rand.
