Its very simple calculation really. Just look at the rest of the world if you're blinded by existing US system. 10s of countries have solved both of these problems in strikingly similar ways (similar as in similar for each problem not across the problems). So, why is US different? Answer: It's not. Majority of US folks need to just grow up to the fact that US humans aren't different than ROW humans and accept what data has been saying to them for generations. No point in being an outlier and trying to defend it tooth and nail.
