That's exactly my point. Back in the days (around the turn of the century) when the power companies were supplying DC power, they switched over to AC because it's much cheaper for them (and really everyone) for several reasons. In order to convince people that they should switch over to AC power (and replace any appliances that wouldn't work with AC) they made a big deal that you wouln't need polarized outlets with AC (like you do with DC).
