The big idea

Even if one person is better at everything, both sides gain when each one specializes in what costs them the least to produce and then trades.

Could Lamar Jackson mow his own lawn? Sure, and he’s probably great at it. But every minute mowing is a minute not throwing passes or shooting commercials. He hires a landscaper, the landscaper earns money, and Jackson earns far more doing what he does best. Both win.

Meet Alex and Jordan. Alex is faster at making both smoothies and sandwiches. But for Alex, every sandwich costs 2 smoothies. For Jordan, a sandwich only costs 1 smoothie. So Jordan has the comparative advantage in sandwiches and Alex in smoothies, even though Alex is better at both.

If each specializes and they trade at a price between their two opportunity costs, both end up with more than they could make alone, beyond their own PPFs. Scale that up and you get Brazil exporting coffee, Japan exporting cars, and the whole global economy.
