Yes, every Canadian citizen is concomitantly a shareholder and a (potential) customer in my model. But the amount you pay is not proportionate to you shareholder status, it's proportionate to how much of a customer you are.
Not all the customers are shareholders, though. Nokia is not a Canadian citizen.
The dividends that you receive are merely the profit distributed. When you walk a sidewalk, you get to do so for free merely because you're a shareholder. The dividend isn't expressed as a cash, but as a variety of services and good that a shareholder can access. If we wanted to just cut every citizen a cheque instead, that would be just fine. In fact, we could just cut a cheque. The service fees are our money.
Your sidewalk example has a minor flaw, in that "use of the sidewalk" is not limited to "customers" or "shareholders." It is effectively a free commodity that as long as it is not used beyond its capacity requires no system of distribution. Just like there is currently no "economics of air," the sidewalk is no longer a part of the system once it is built. Sidewalk
maintenance is a distributed good governed by the rules of the system. Someone who has opted out in the way I described may walk on the sidewalk, but if they try to call for maintenance services on a particular stretch of sidewalk that is of importance to them without some sort of status they won't get it. Sidewalk
construction is similar in that no one is asking the opinion of the non participant where the sidewalk should be built.
And Nokia, while neither a citizen nor even a human (which is, or at least should be a prerequisite), is in fact both 'customer' and 'shareholder' and thus also lacks any distinction between those two states. They "give and take" in the same basic ways as a citizen even though they are not one, as long as they choose to participate in Canada.
Now, when you circle back to the question of how that 'give' is proportioned relative to how the 'take' is proportioned you meet economics head on. Every participant (being both shareholder and customer simultaneously) perceives a balance between their giving and taking that is acceptable enough to have them continue participating. Looking at my list of requirements to stop participating it is obvious that this "acceptable enough" does not really set a very high bar. One has to be
really seriously dissatisfied to take the required action to stop participating. Nokia isn't abandoning the Canadian market. Canadians are neither emigrating in droves nor are huge numbers of them making the effort to become an in place nonparticipant.
Which is important because near as I can make out
no one is perceiving a balance that is very far above the minimum acceptable. The poor ***** like mad about their balance of give and take, but so do the rich, and everyone in between. Everyone believes that their own complaints are valid, while the other complaining people just can't see how good they have it...they blame a problem in the other's
perception of the balance as related to them rather than the balance itself. And they apply all this to their own balance and continue to find it adequate, though barely.
