Income of richest households vs. tax on high incomes

During the last 90 years the U.S. has experienced large changes in the share of the total national income controlled by the richest households. The (pre-tax) share of the richest 0.01% of households, for example, was under 1% in the late 1970’s, but over 5% in the late 1920’s and in the years 2005 and 2006.

Over the same period, income tax rates on high incomes varied greatly. The top income rate fluctuated between over 90% (1950’s and early 1960’s) and under 40% (1920’s and 1987 to the present day).

As is evident in the chart below, those two phenomena are strongly negatively correlated over time. The correlation factor is about -74%. Of course, correlation does not imply causation, but even if high tax rates on high incomes do not directly translate to smaller (pre-tax) income for the rich, the correlation supports the notion that inequality in income is determined to a large extent by public policy rather than by an “impersonal phenomenon, the market price”.

Data: Income data are from Thomas Piketty and Emanuel Saez, “Income Inequality in the United States, 1913-1998”; updated version and updated data files available at Saez’s website. Tax rate data are from “Personal Exemptions and Individual Income Tax Rates, 1913-2002”, an IRS publication.

Implementation of democratic mass media

The aim of this post is to provide some particulars for the proposal for democratic media which I made:

Using public funds, “media sections” (TV and radio channels, newspapers, book publishers, etc.) are created and sustained. The media sections are controlled by citizen-editor boards, a role that would rotate within the entire population. Each citizen-editor board has a budget and complete control over a section – i.e., over a certain part of the public media – in the same way that present-day editors and media outlet owners have today.
