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. I feel at this moment more anxiety for the safety of my country than ever before, even in the midst of war.

– Abraham Lincoln (1809-1865) letter to Colonel William F. Elkins, 21 Nov 1864.
