From certain perspectives it hasn't been that great of a state even with massive oil incomes. It will probably continue to be a state with massive wealth inequality and repressive government theocracy. It'll just have more social unrest to possibly change the status quo. Maybe people will really start to demand change there.

It will be like any other country in the world. We should hardly feel sorry that they’ll no longer be ridiculously pampered and looked after by an underclass of mistreated immigrants. They have enormous opportunities, both in other available resources and in a capital overhang, to make their way.
