I really don’t agree with your last sentence though. “Fixing” problems before they arise is exactly why we, particularly governments, already spend millions on the promotion of wellbeing and heathy lifestyles in order to prevent health issues in later life.
I’m pretty familiar with the differences in life expectancy statistics caused by health inequality. I’m not sure that you can truly promote wellbeing in a world where people are treated like they’re vastly less valuable.
When I was a (hungry and impoverished) child, I was optimistic that hunger and poverty could be solved.
As an adult who teaches the study of humans, it is quite clear that the solutions are convenient enough, so will not be attempted.
Hungry children it is.
