100 years ago the richest man in the world could die from a simple infection because there were no such thing as antibiotics. People take for granted so many things we have in the modern world, they want some form of utopia right now. Perfect is the enemy of good
And now the poorest man in the world will die from the same infection because he can't afford the antibiotics, or has no access to a doctor who can prescribe them to him. What's the difference between something existing but being impossibly expensive vs not existing at all, except for the ultra rich?
Are you arguing that access to healthcare for the global poor isn't the best it has ever been and hasn't been getting better every year? Because we know that's the case.
