much like the slave revolt event under slavery, free market should have a "subprime crisis" random event associated with it, during which the government will be forced to pay 5000g to bail out the corporations. if there's a spare GM or a settled GM, then the player can choose to sacrafice the GM (assign to permenantly head a regulation committee) and cut the bail-out tag to 2000g, if the player founded any corporations, then an additional option is available so that the player may choose to eliminate the bail-out by receive half of the benefits provided by the most widely spread corp the player founded, for the next 20 turns, so that the corp can help pay.
yeah, i know, free market is arguable not that great to warrant a nerf, but i just feel the need to vent after recent events. and besides, this addition doesn't have to be just for FM; I mean, why is slavery the only civic with built-in negative random event, are the other civics so much better that they are disaster-proof?
