Let me repeat my idea from another thread:
Why doesn't emergency build affect HAPPINESS levels like cranking up production did in SE3? Wouldn't it provide a reasonable disincentive to use emergency build if it costs one or two percent happiness per turn? People do get cranky and difficult when you force them to work 80+ hours a week...

I presume that even aliens like to have time to spend with the kids/hatchlings/sprouts and the spousal unit so they can get their nookie.

If it cost 20 percent happiness to go into emergency build for a year, you'd also get DIMINISHING RETURNS as the happiness level affected production bonuses. Does this not seem reasonable and realistic?
