premise: Authors like Brand and Toffler understood the rise of what today we call libertarianism, with its cross-pollination between cultural trends (do-it-yourself rock and roll, homebuilding, computer building, etc., symbolized by the Whole Earth Catalog, the Sex Pistols, and the Apple II) and economic trends (the rise of the entrepreneur as hero, the brand of me, and ever-lowering barriers to the flow of capital from market to market).
hypothesis: Libertarianism is 25% more popular today than in years past.
