Imagining the Future--the Founders

John Fea comments on Sen. Mike Lee's Am history--good read.  Lee wrote that Alexander Hamilton could never have imagined the sort of big government we have today, implying that therefore such government was somehow illegitimate.  Fea points out that neither Hamilton nor the other founders could have imagined the society and economy we have today.  I'll go on to note that while Franklin and Jefferson IIRC wrote about the U.S. filling the continent and the expansion of the populace, as is usually the case they just imagined more of the same: more people, more farmers, etc.
