Yesterday's Liberalism vs. Today's

Many people today will argue about the fact that we as a country have lost the meaning of what this country was built on, and what our founding fathers' meaning of liberalism meant verses what liberalism means today. Has it changed? Are we to change our way of thinking as a country, or has that already happened to us without realizing it? In Nathan J. Beacom's article, he writes, "Political liberty... is the freedom not to be a slave; it is to be in command of those liberties of speech, of movement, of thought, that are proper to the development of virtue and the pursuit of a flourishing human life." What does Beacom mean by this? Have we forgotten the difference between political liberalism and liberalism, or worse so, created such a huge gap between the two if there even was a difference? Here are my thoughts: in the time of our founding fathers, it was a time where people who made a name for themselves worked their hardest to make their way to the top.
