I can't speak for others, but I find the value of a quote to be almost completely independent of its originator. (exception being when the originator is someone like Hitler; that's a short list, though)

I'm not a fan of this particular quote, though, because I can't tell if it's sarcastic or serious. (I've never played the lottery, but I wouldn't expect it to make me feel rich; voting doesn't make me feel powerful. I'm just not sure what it's attempting to communicate.)

EDIT: what orthonormal said. Also, before anyone docks me for the same reason, the reason I would refrain from quoting Hitler (assuming he ever said anything worth quoting) is because I know that many, many other people can't separate ideas from sources. Plus why would I be reading Mien Kampf??
