Adam Grant was the person who created the wealth of nations. He concluded that specialization and trading are better for everyone involved.
If you don’t specialize and trade, you’ll have to do everything yourself.

Instead, by specializing everyone’s opportunity cost improves.
The PPF profit possibility frontier helps understand the relationship between producing two products,
For example, if the us is producing 500 planes and it could use the same effort to produce 2000 shoes, For every 1 plane they produce, they leave our 4 shoes.
If China can produce 100 planes or 800 shoes with the same effort, china for every 1 plane produced, leaves out 800 shoes.
It may seem that the US is better off here and should not trade, but if the US trades planes for shoes, they’ll be better off (need to learn here)
Point outside the PPF curve is an impossibility The point inside the PPF curve is inefficiency. How do you maximize efficiency? By specializing and trading.
Self-sufficiency is inefficiency
