Here is a sobering quote by Abe Lincoln:
"I see in the near future a crisis approaching that unnerves me and causes me to tremble for the safety of my country. . . . corporations have been enthroned and an era of corruption in high places will follow, and the money power of the country will endeavor to prolong its reign by working upon the prejudices of the people until all wealth is aggregated in a few hands and the Republic is destroyed."
-- U.S. President Abraham Lincoln, Nov. 21, 1864
(letter to Col. William F. Elkins)

Some people expressed doubts about its authenticity, given Lincoln's work as an attorney for railroad corporations! It was an interesting job tracking it down and verifying its authenticity.
