I have only this to say about Freedom Through Equality: every deck that I've put it in, there hasn't been a single game, not even one game, that I have won when I didn't score this card. Not a single one. One game I even won with only 4 "real" agenda points in my score area. I can't tell you how many games I would've lost stranded at 5 or 6 points without this card.
It's purely anecdotal, but this is the most compelling argument for a card I can come up with. This card wins games. Slot a couple and try it out. You won't be disappointed.
Also it's pretty good with Spy Camera.
