Should Leftists and Progressives trust Pfizer and Big Pharma?

The Left has always had a strong tradition of emphasizing the importance of science and empirical understanding of the world. Remember that foundational socialists such as Pierre-Joseph Proudhon, Karl Marx, and Friedrich Engels considered their approach to economics as "scientific socialism." Marx himself admired the scientific advances made possible by Capitalism. As Leftists, we should not dismiss the labour of the workers of these pharmaceutical companies, nor should we align with conspiracists, conservatives, or fascists.
