https://en.wikipedia.org/wiki/Liberalism
Liberalism is a political and moral philosophy based on the rights of the individual, liberty, consent of the governed, political equality, right to private property and equality before the law.
By “private property,” what is meant is “the means of production.” Liberalism is the philosophy of the bourgeoisie, otherwise known as the capitalist class.
The French & American Revolutions were Bourgeois Revolutions. The US Founding Fathers, who were wealthy land owners and chattel slave owners, intentionally constructed a Bourgeois Democracy, which was never meant to represent the working class, and it never has, despite later allowing non-landowners, women, and non-whites (those not re-disenfranchised by the carceral system, anyway) to vote.
