More likely it would mean that no one would make such devices, if they cost millions or billions, and there aren't enough people to buy them. So the only things that will be made will be the things that the makers actually know can be sold. Maybe that means that the TVs won't be as big, and gadhets won't be as fast, but I'm sure these wealthy types will manage somehow.
I don't think "tech elite" will be much happy with this fate - living in the small enclaves, spending large resources on the defense (80-90% "useless population" will fight very hard trying to capture these cities) and even don't having hi-tech products!
