Buying the End of Disease?

Rowan Hooper does on interesting exercise, considering what medical advances we could purchase for a trillion dollars (https://www.theguardian.com/news/2021/jan/28/could-we-cure-disease-with-trillion-dollars-coronavirus). Hooper points out that, although it sounds a lot of money, it is quite easy for countries to create such amounts, by processes such as quantitative easing (they did it for the financial crash). A number of items are presented for investment consideration such as e.g. funding universal health care in e.g. Ethopia, to demonstate how it could be done, as well as emphasing the health gains implicit in having such systems. The opinion piece also considers the investments needed e.g. to:- completely solve the Covid-19 pandemic, deal with malaria and its mosquito vector, fund vaccine research for a variety of ailments, set up systems for detecting the next pandemic et cetera, et cetera. I agree that a trillion dollars could purchase an awful lot of medical improvements (it's finance that generally holds lots of things back). The trouble is, as I see it, that humans will always be a medical problem for their own (as well as other) species. We are just too good grabbing all the limited resources, being a resource ourselves for other organisms and damaging ourselves and our environment by our behaviours (humans cause many of their own diseases e.g. by eating the wrong things, drinking too much alcohol and smoking etc). I don't think we can ever abolish all causes of ill-health. We could, with the right investments, certainly improve things for the majority. Having said that (to quote Albert Einstein) "Two things are infinite: The universe and human stupidity; and I'm not sure about the universe". I suspect that human stupidity will ensure, that ill-health is always with us, no matter how much we spend on its alleviation.
