; Human Capital Landmarks
: '''The 'GI Bill' (USA)''' → After WWII, the US paid for "Veterans" to go to "College." It "Exploded" the "Human Capital" of the nation, leading to the "Greatest Prosperity" in US history.
: '''PISA Rankings''' → A "Global Competition" to "Measure" the "Human Capital" (Math/Science skills) of "15-Year-Olds," predicting which countries will "Win the Future."
: '''Early Childhood Education (Heckman Curve)''' → Nobelist James Heckman proved that "Investing in 3-Year-Olds" has a **10x Higher Return** than "Investing in 20-Year-Olds." (The 'Earlier' the better).
: '''Non-Cognitive Skills''' (Soft Skills) → The "New Frontier": "Grit," "Teamwork," and "Empathy" are now seen as "Capital" just as important as "IQ."
