15. Is Income Inequality Self-Correcting in Democracies?
Income inequality may be self-correcting in a democracy. Can we work through how that would work?
Hints:
A. Each person gets one vote
B. The government sets the level of redistribution — i.e. the level of taxes and the level of government spending on welfare, unemployment etc.

20. Guidelines for Thinking About Policy
Seek out thinkers who disagree with you
Always respond to the strongest version of the argument made by those who disagree with you
Do not hold strong views in areas where you know little
Recognize that we all know little in most areas
Beware confirmation bias when receiving new information
Do not discount new empirical information that challenges your current beliefs

21. 2017 Tax Reform Legislation
Reasonable people disagree about the long-run growth effects of cutting taxes on corporations
Less debatable:
The most recent tax overhaul is regressive, particularly after the first three years
Cutting taxes in 2017 is pro-cyclical – i.e. this bill increases budget deficits at a time when unemployment is very low and the economy is strong
Note: Most Democratic budget proposals are also pro-cyclical, though on the spending side
