Sure, I’d agree that naïve capitalism is a big factor in the misuse of science, but the atom bomb was invented to defend against the German and Japanese imperialism of WW2.
Also, without capital, how is good science supposed to be conducted, though?
The days of cheap and easy science are long gone and proper, “good” science is even more expensive than ever.
For example, see the modern difficulties with even the “gold standard” of double-blind research in medicine.
