Correlation is not Causation

I spent most of the evening reading Underbelly posts, so this link is probably due to Buce:

On Oct. 22, 1986, President Reagan signed into law the Tax Reform Act of 1986, one of the most far-reaching reforms of the United States tax system since the adoption of the income tax. The top tax rate on individual income was lowered from 50% to 28%, the lowest it had been since 1916.

About thirteen years from 1916 to 1929. About thirteen years (plus the Clinton Administration) from 1986 to 2008.
