idk, call me crazy, but maybe enforce anti-trust laws, don't allow monopolies, etc. seems sensible to me. don't let a single corporation reduce the amount of ram the world can buy by 40%.
and modernise the laws against price fixing and so on, so that you can actually punish this sort of thing
letting one american company destroy the world economy seems pretty dumb if you ask me. maybe... don't let them do that???
