Large corporations

It might seem that large corporations or entities are left out of this group system.

But these bodies really have nothing to do with government ( apart from their practice of exerting pressure on a government to further their own ends ).

We still need large corporations to do things which smaller ones cannot do, like provide high-tech goods and services which a smaller body could not possibly do.  Transport, computers and other large technically complex systems are a case in point.

It might be nice to think that most operations could be operated at the local group level, but look at the cost and complexity of something like a semiconductor fab plant, which we totally rely on for high-tech chips, and imagine where a few cooperating groups are going to get the resources to build and operate something like that.

But I see no problem in a corporation employing people from a whole collection of groups.  In fact it might even be an advantage to both parties. The groups already have a leadership structure, which can negotiate with the corporation over wages and conditions in a similar, but hopefully less argumentative way, than the unions do now.   And the better communications of that system should lead to better outcomes for both 'sides'.

On the management side, a corporation should see that it will have less possibility of pressure tactics working, when the upper levels of government getting the pressure are directly accountable to the lower levels, where the workers for that same company are.  As well of course, are groups who have no involvement with the operation of the company, but may not like what they do, eg environmentally.  Those too can apply pressure, both vertically through their leaders, and horizontally to their neighbouring groups.
