this man might disagree with you...
the 'system we have' is corrupted to benefit and enrich the stock portfolios of shareholders and bank accounts of big pharma executives. it's the individual scientists that have a dedication to research and eliminate diseases that infect humanity, which is a noble cause. pfizer, the company itself, doesn't give two sh!ts about 'benefit(ting) the entire human race'. they are concerned with profit, and profit only.
please spare me the specious argument that people are only motivated by selfish reasons, such as money. most are absolutely not. sure, doctors like the money they make, but do you believe for one second that all, or even most people become doctors because they just want to make oodles of cash? teachers - oh yeah, they make major bucks. they obviously become teachers just so they can be filthy rich and take summers off. research scientists? i'm sure some make good money - but the ones i've met in the past are hardly rolling in wealth. the majority of these people educated themselves to do these things because they want to help others. this is why people do what they do - they are more concerned with helping others - to help others with their medical issues, to teach others to learn, to discover new things that benefit the rest of the planet - not to get personally rich.
but this is on the individual level. at the corporate level, there is certainly a kind of corporate sociopathology, that has a disregard for what is best for humanity, and a focus on what's best for the corporation and its stockholders. which translates into how much money they can generate and keep for themselves. and certainly there are many individuals who care more about making profits for themselves and have no concern whatsoever in doing what is actually ethical.
so yes, if pfizer did find a cure for AIDS tomorrow (or cancer or whatever the illness du jour is), it should most certainly be stripped from them to benefit humankind.
and that's exactly why they DON'T come up with that cure. it's not fiscally responsible to their shareholders and board members to create a cure that they know is ethically responsible to share freely with the world. this is what hinders any type of progress - they are far more concerned about their profits and bottom line than they are actually trying to benefit humanity. and anyway, it's not profittable to eliminate the cash cows like AIDS or cancer. it's far more profittable to create treatment drugs for the symptoms than it is to eliminate the cause of the symptoms.
keep in mind, this 'system' you speak of, the system of BP, is part of the axis that is attempting to do away with vaping if they had their way. BT works the same way. by justifying this system by implying people's primary motivation to do what they do is greed, you're helping to perpetuate this corrupt system. and that's not going to help with ending their attempts at vilifying vaping, or trying to eliminate it altogether.
