Up from Libertarianism?

"But wait. Did 'early Americans consider themselves free'? White Americans probably did. But what about black Americans, and especially the 90 percent of black Americans who were slaves? Slaves made up about 19 percent of the American population from 1790 to 1810, dropping to 14 percent by 1860. (In that period the number of slaves grew from 700,000 to about 4 million, but the rest of the population was growing even more rapidly.) Did Mr. Hornberger really forget that 4 million Americans were held in bondage when he waxed eloquent about how free America was until the late 19th century? I know he isn't indifferent to the crime of slavery. But too many of us who extol the Founders and deplore the growth of the American state forget that that state held millions of people in chains."

David Boaz in Reason argues with Jacob Hornberger over whether past eras in American history offered greater freedom.
