And, critically, how much are we willing to collectively sacrifice to move that percentage of people in a positive direction?
This begs the question, at least to some extent. A big lesson of modern economics is that lots of things are win-win.
For example, if you could eliminate years spent in prison by spending more on K-12 education, that looks like a big sacrifice if you don't have the prison counterfactual to compare to, but it's potentially the cheaper path.
