Interesting Principles of Economics

This is a textbook, but it is written in a very interesting way.

Why can trade make everyone better off?

Everyone has their own strengths and weaknesses; each person can use their strengths to trade with others and make up for their weaknesses. For example, suppose there are farmer A and farmer B: farmer A can produce 100 kg of beef and 1 kg of potatoes in a week; farmer B can produce 100 kg of potatoes and 1 kg of beef in a week. If the two do not trade, farmer A will be sick of eating beef while farmer B will suffer from malnutrition; if the two exchange their beef and potatoes, both will live well.

Why are there so few luxury taxes?

Suppose we impose a tax on yachts; if the tax is too high, the rich will spend their money on other luxury goods, and the ones harmed will be the workers in the yacht manufacturing industry.
