I've always kinda thought that if you could not establish a fairly credible attribution, the safest course of action is to avoid the quote. "When in doubt, leave it out."

Granted, this isn't an academic venue.

However, the basic meaning I pulled from Lindy's post was that in a liberal democracy--actually, in any socio-economic setting, I suppose--there can arise powerful, somewhat obscure forces that the public in general would do well to keep an eye on.

It really seems self-evident when you just come out and say it, but all-in-all it's perhaps not an unreasonable observation.

And you can quote me on that
;-)
