We're already seeing talks of eliminating preexisting conditions. Insurance companies would be stupid not to buy consumer data to look for things. The GOP have been wanting to gut Obamacare since day one, which means democrats are going to outflank Trump by eliminating preexisting conditions because "Think of our poor, little insurance mom and pop small businesses!"
May even be some GATTACA style eugenics shit where people are denied jobs because of pre-existing genetic medical condition tendencies. It may be technically illegal even then, but that won't stop corpos from mysteriously not hiring those people.
Unlike in the treats tho I won't be able to sneak aboard a space shuttle so as always reality is worse than the dystopian fiction could have predicted.
