Here's your remedial:
1. Classical liberalism
a. “The American intellectual class from the mid 19th century onward has disliked
liberalism (which originally referred to individualism, private property, and limits on power) precisely because the liberal society has no overarching goal.”
War Is the Health of the State
b. Wilson and the
Progressives tried to make war socialism permanent, but the voters didn’t agree. They (Progressives) began to agree more and more with Bismarckian top-down socialism, and looked to Russia and Italy where ‘men of action’ were creating utopias. Also,
John Dewey renamed Progressivism as ‘liberalism,’ which had referred to political and economic liberty, along the lines of John Locke and Adam Smith: maximum individual freedom under a minimalist state.
Dewey changed the meaning to
the Prussian meaning: alleviation of material and educational poverty, and the removal of old ideas and faiths. Classical liberals were more like what we call Conservatives.
c. “Finally, Dewey arguably did more than any other reformer to
repackage progressive social theory in a way that obscured just how radically its principles departed from those of the American founding. Like Ely and many of his fellow progressive academics, Dewey initially embraced the term "socialism" to describe his social theory. Only after realizing how damaging the name was to the socialist cause did he, like other progressives, begin to avoid it. In the early 1930s, accordingly, Dewey begged the Socialist party, of which he was a longtime member, to change its name. "The greatest handicap from which special measures favored by the Socialists suffer," Dewey declared, "is that they are advanced by the Socialist party as Socialism.”
John Dewey and the Philosophical Refounding of America by Tiffany Jones Miller - National Review Online
d. “DEWEY'S influential 1935 tract, Liberalism and Social Action, should be read in light of this conclusion.
Again: "...repackage progressive social theory in a way that obscured just how radically its principles departed from those of the American founding."
So, you can see that the Left definitely is not responsible for the greatness that is (was?) America.
Ain't knowledge great?
