The Senate exists only and exactly because the Minority was worried about being overwhelmed by the Majority.
One of the brilliant balances designed by Our Founders (tm) was that the Minority always had a strong voice.
Who was in the minority in 1776-1800? The states of New England and Pennsylvania. The warm and temperate and most fertile states had the greatest population.. the only way to get the Northern States to sign on to the Constitution (after the disastrous failure of the Articles of Confederation) was to Guarantee each State the right to have their say, and to protect the minority population against the majority.
