Lincoln was prophetic in his fears for the safety of the Republic.
"I see in the near future a crisis approaching that unnerves me and causes me to tremble for the safety of my country. As a result of the war, 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."
The passage appears in a letter from Lincoln to (Col.) William F. Elkins, Nov. 21, 1864. source
