No, Pfizer advances jack shit. They get massive state funding, as do the rest. They then turn around and abuse their consumers. If you don't believe me, which would be pathetic, you could try googling "Pfizer malfeasance."
"We"? Define "we," please. It isn't like the rulers of countries just decided one day that they were going to implement some reforms and transition out of Feudalism, because they thought that on the whole, it would just work out "better" for "us."
(Please also define "better." Democracy is not better than monarchy from the monarch's point of view.)
These changes were brought about through bitter class struggle, and bloody revolutions, through the noble sacrifice of many revolutionaries.
Please at least respond and refute if you're going to downvote me immediately upon seeing marxian terminology.
Your paradigm of thinking is so fucking simplistic and dumb, you should really take a look at how much sense it makes and consider finding a new one.
