So there you have it. Late Stage Capitalism Failure. No ability to make a bajillion dollars in rent-seeking profit. So F it! Let the people die.
Well, if capitalism is the problem, then why don't the socialist/communist countries develop the drug instead? Or alternatively, the community could come together and they could work on coming up with the treatment as a group. But we all know that neither of these are likely to happen. Researchers need money to live, labs need money to run.
Big capital put this idea inside the heads of many people living in the West and until today they really believe there is countries who are socialist/communist. Neither the GDR nor the UDSSR or China are examples for countries like that and people who know about politics, economy and society know this as a fact.
It is easy for you to criticize all alternatives at once because you have never seen any and chose to believe what the ruling party (=capitalism) makes you believe.
