That part is working. Yes. Good job!

Is the deterioration of the global market not mainly a result of neglecting to keep monopolies in check and provide adequate regulation?

As Marx points out in Das Kapital it's not possible to keep monopolies in check and provide adequate regulation since they will find a way to capture the government and its regulatory agencies, so that they work for the capitalists and not the public. So what Hossenfelder failed to acknowledge is that no civilization knows how to defend its regulatory agencies from elite influence. It also fails to address matters like the uneven distribution of wealth, which leads to failure of the state and a whole lot of violence.

And that deterioration of the global market was well underway at the time that capitalism drove the development of penicillin. Capitalist interests also drove the triggers of WWI, the overreach of the Treaty of Versailles and the consequential rise of the German Reich. And, capitalist interests figured largely in the advancement of the holocaust from concentration camps and a deportation policy to an annihilation policy and the genocide machine. ( Behind the Bastards podcast recently released a two-parter on Reinhard Heydrich, the lynchpin official who developed the whole process, worth a listen!) so as capitalism drove penicillin development to save fallen soldiers from infection, it also facilitated the driving motivations for conquest and belligerence, hence the war itself that shot those soldiers up in the first place.

And when I watch Hossenfelder's videos, usually I can count on her to be more thorough than she was regarding the failures of a system, but it's not the first time her biases have informed her content.
