I know it is desirable to keep a near-100% approval rating for most of the game to grow your population as quickly as possible. But what about at the very end, when practically all your planets have filled up, and you've decided to see how many points you can milk out of the game? Is there any penalty to my social score if I do the economically logical thing of raising taxes to send my approval down to ~21%? If nobody knows, I suppose I can test it fairly quickly, but I was wondering if someone already knew offhand.
