Sure, but varying demographics can alter those reasons, and technology advances can cure some of the limitations. Lawrence of Arabia said that it wasn't machineguns or mortars that made the Arab Revolt against the Turks and their German masters feasable, but the availability of tinned beef, giving the tribesmen the opportunity to wage war without having to forage for rations. Amateurs and junior officers study strategy and tactics, successful generals and professionals sweat the logistics....
Still, you'd think the sharpie native Paiute or Goshute who first noticed the Mormons a-coming to the Salt Lake area could have done real well for himself with a couple of lemonade stands along their route....
I predict there'll be a couple of Home Depot managers somewhere who'll have their year-end figures looking a LOT better than they'd envisioned before too awfully long....<p. -archy-/-
If you're talking demographics, your timescale just jumped to generations, and that might have its own problem, as I will discuss below.
As for technology: can it cure enough of the limitations?
One thing I have noticed--maybe it's an anomaly and you can correct me on this--is that there is one event that turns libertarians into mere conservative Republicans, and that's becoming a parent. In short, every active libertarian I know has ZERO minor children.
Where does the next generation of libertarians come from? Most libertarians I know became such due to exposure to YAFF in colege--they usually don't have libertarian parents.
