Suppose Mars needs 24 million Martians to produce 1 starship per year and it needs 4 million workers to make 1 trillion tons of food per year. Venus only needs 2 million Venusians to make a starship and 2 million workers to make a trillion tons of food. Suppose each planet has 48 million people and dedicates half of workers to each sector. The most the Martians can produce without trade is 2 starships or 12 trillion tons of food. The most the Venusians can produce without trade is 24 starships or 24 trillion tons of food.

If you computed the average salary on Marsaftertrade you would find it grew to $250,000. If you computed the average salary for the Venusiansaftertrade you would find it grew to $1,083,333. In what sense did the Venusians get the better deal? In what sense did the Martians get the better deal?
