The reality is, lots of people have been asking for just that for a long time, and it's not come to fruition because it is an extremely difficult thing to do.
Consider Native Americans. They wanted change for years, and essentially had to start casinos to begin making headway. Even now, a material number of tribes and reservations are still racked by poverty, and are unable to participate in the vast majority of legal industrial activities at scale. The system has not changed for them, some of them have simply been forced to find a method of adapting to the economic system that we have.
Blacks are another example. They're a group that has agitated for change for what seems like an eternity. It's similarly doubtful that the system will change for them either. The ones who have found success are the ones willing to leave their neighborhoods and participate in the larger economy not on their own terms, but on terms set by that larger economy.
I actually would like for a new economic state to take hold that would include people who concerned thinkers have termed "those left behind". It's just that, given the interests embedded in the current system, I can't see how it will change. As I pointed out, many groups have tried previously, and tried for a very long time, yet we still have the same system in place. The best we seem to be able to do, is to allot a few set asides for the purposes of elevating a chosen few of "those left behind". I suspect we'll follow a similar path in the instance of rural "left behinds". But my suspicion is that the inertia in our system will mean that wholesale change to accommodate the majority of "those left behind" is not likely to occur.
