“….it is dangerous…to alter the Qualifications of Voters. There will be no end of it. New Claims will arise. Women will demand a Vote. Lads from 12 to 21 will think their Rights not enough attended to, and every Man, who has not a [penny], will demand an equal Voice with any other in All Acts of State.”
John Adams, Founding Father and 2nd president of the United States 1797-1801
(Source: John Adams letter to James Sullivan, 26 May 1776)

At the Constitutional Convention in 1787 Alexander Hamilton proposed that the president be elected for life, effectively making him an elected king. That went over like a lead balloon.
Note: Alexander Hamilton got less of what he wanted in the Constitution than anybody else and then did the magnanimous thing after the Constitutional Convention of working harder than anybody else to get the necessary nine states to ratify the Constitution to make it the supreme law of the land.

At the Constitutional Convention in 1787 Benjamin Franklin proposed that the President should serve without pay and originally wanted the executive branch to be an Executive Council of several people instead of just one President.
