I doubt that.
Yankee tax dollars paid for rural electrification, which gave you Yankee invented electric light and Yankee invented air conditioning.
Tax dollars shouldn't go to pay for anything of the sort. That is something that is a private industry issue and before the war was illegal under every state Constitution as well as the general government.
Not just any Northerner is a Yankee; there are good Northerners. You should read the article by Clyde Wilson that Benson refers to for a more precise characterization of a Yankee. For example Thomas Edison, who was born in New Jersey, was certainly not a Yankee; the inventor of air-conditioning was a New Yorker, so he doesn't qualify as a Yankee either. It is difficult for me to imagine a Yankee actually making a positive contribution to civilization. There may have been one or two who did, but I certainly can't think of any off hand.
