If you want to blame people for the proliferation of viruses like Covid, look at far-right denial politicians like Donald Trump and Jair Bolsonaro.
On the other hand, Capitalism was the only reason we had a vaccine as fast as we did.
And as for $20 Billion to vaccinate the world... when is the last time governments got organized and cooperated together to solve a crisis problem? When is the last time the US "estimate" did not run over budget? And why didn't US government researchers, that were still funded despite DJT's vitriol, roll out a vaccine faster than corporations?
The answer is simple: capitalism is a positive thing, and our best hope for combatting global vaccine pandemics. Capitalism is certainly not at fault for a disease that started spreading under secrecy in a Communist nation.
