Variable-sum suggests that if we miss on creating opportunity for that kid from a poor neighborhood, we all do worse. He's either creating value for all of us and everyone does better because he is doing better or he is not and we're all doing worse.
Zero-sum suggests that if that kid comes across a border or leaves a bad neighborhood to get a job, it'll be stolen from us. The only way he gets ahead is from us falling behind.
In 1980, the acceptance rate at UCLA was about 75%.
Today it is close to 10%.
Today it is close to 10%.
We even have a zero-sum worldview when it comes to education, to knowledge, to learning - domains that are so demonstrably variable-sum as to make them the perfect examples of variable sum. If you give me a dollar and I give you a dollar, we leave the exchange no better. If you give me an idea and I give you an idea, we might both be better off. (Or worse off. It could be that we exchange really dumb ideas. This is, of course, the domain of variable-sum.)
We need to do better at making people's lives better. The simplest predictor of future returns is present investments. Any community that wants to prosper has to look for reasons to invest more, not less. We could start with increasing the capacity of our great public universities, making them tools for more young people to create a better future. Because when we leave some young adult's potential untapped it reduces the potential of all of us.
One of the most curious consequences of realizing that you live in a variable sum world? The distinction between selfish and selfless begins to blur. We have to make lives better for other people to make our own lives better. It's a fairly cool reality we've gotten ourselves into.
