I'm not clear on whether the future difficulties you describe in the first paragraph of your post are intended as an exercise in imaginative world building where the socio-political possibilities are open-ended or a future that in the real world you consider inevitable.
In any case, much of the social, economic, and political conflict you posit for the future in your first 3 sentences is already a fact. So, on the one hand, its not hard for me to imagine these conflicts continuing. But, on the other hand, why should they? Why must we continue to allow inequalities (in access to material goods, education, employment, healthcare, housing, political participation, etc.) we know to be counter-productive to the wellbeing of the vast majority of the citizenry, to continue. After all, the intellectual capacities necessary to conceive, construct, and implement advanced technologies certainly indicates that we have sufficient brain-power to solve issues of gross inequality, if we set ourselves to that task.
Much of the inequality and injustice you spoke of stems from the structure of our social organization - in public government, as well as in private business, the model is hierarchical; power is highly centralized; and, of course, wealth and privilege are concentrated exclusively at the apex of that pyramid, while the overwhelming majority of a politician's constituents and a CEO's employees occupy the base - and those citizens at the base happen to contribute most of the energy and agency without which all above them could not maintain their status - i.e., invert the pyramid and what happens ... immediately? The structure falls. That demonstrates what's fundamental and what's not - every strata of that pyramid above the base ultimately depends upon the integrity of the base.
Now, in some (though not all) organizations--such as government--more productive models are available. The advanced technologies we already possess (the World Wide Web) would allow us to easily transition from the present, hierarchical pyramid with its highly centralized power (a representative but merely nominal democracy) to an actual democracy wherein every citizen directly votes on all pertinent issues (and, I guess, pretty much all issues are pertinent). Such a change would allow the majority (nee, We the People at the Base) much greater political participation. At that point local, State, and Federal Legislatures and court Justices (who are either elected or appointed) could restructure the laws and overturn the judicial decisions which gave for-profit corporations the same legal standing that you & I supposedly enjoy in courts of law, and we would be well on our way to a far more sane, healthy, and just world.
Then again, if it was your aim all along to imagine a future dystopian police-state, I've probably bored the feces out of you and wasted your time, in which case I offer my sincere apologies. This is my first attempt at an answer here and I don't really have the feel of the site yet, OK?
