@Naturegirl,
That scenario makes perfect sense to me! However, I think it's the minutiae of production and simple volume of global supply and demand that causes problems, among other things.
My two cents: [and I am not an economist so sorry for what will inevitably very strange thoughts]
I think, conceptually, Capitalism as a function of predicting... demand in products, for lack of a more specific definition, makes a lot of sense. A centrally planned economy, at least on a national scale, is simply not feasible--it's too damn hard for a group of bureaucrats to understand the real needs and wants of a large group. In fact, even in the social democracy that the US kind of practices (and many other countries actually practice to fairly good effect) fails to understand the substance of human need. This may be an obvious statement, but in my opinion, economics =/= the accurate prediction of mass satisfaction.
It facilitates the survival of a large part of it's [unwilling] participants--or at least explains it, but doesn't do much raise their quality of life--a metric which is, in and of itself, probably quite.... malleable in terms of what the average persons excepts it to be.
And of course, left UNCHECKED, Capitalism--as a system containing many corporate entities--completely destroys any semblance of freedom within a highly structured society. It places the corporation above the individual or even the collective good. All you have to do is look at 19th Century America to see the evils that lurk in the dark places of economic thought--but I won't go into detail here.
How do we fix this? It's a mess, and honestly, I think people might be too big of bastards to actually change to a system where everyone can find some semblance of peace and real freedom...
But regulation is a good place to start. As other have pointed out, most of the resources we need to survive are produced in larger quantities than we actually consume, and should probably be made available publicly for little or no cost. Corporations often complain that regulation will stifle productivity, or at least competitiveness, but there has to come a point when SOMEONE says, that just doesn't matter--while our technology has advanced exponentially, along with so-called labour-saving devices, the amount of time, energy, and ultimately LABOUR we put into our careers has remained pretty much unchanged since basically 1869, which is when Grant made the eight-hour work day a national standard. Of course, it's difficult to measure the change in workload in such a rapidly changing labour environment and over such a long period of time, but generally speaking with the amount of and cost of education to get a well-paying job, the expectations beyond the minimum requirements in pretty much every career, and other factors (like the rise in cost of housing) means that people are working harder and for less than they have in a while. Not to mention several economic depressions...
And I'm pretty much just talking about the US there, needless to say in many other countries it is even worse--fuck, slavery by any other name is still practiced in many places in the world.
Beyond that, I think the larger change has to in the socio-political realm. It's not enough to simply regulate the current environment, big changes have to be made. If you're going to REQUIRE people to be part of your society from birth with no chance to consent to that agreement you have to at least abide by the social contract (We give up some freedom for protection, BUT we also recognize that even the strongest among us are not so strong that they cannot be killed by the weakest, in essence, we are all equals so we agree to play nice) in the traditional sense, but also economically--no one is so important that they deserve many hundreds of times more wealth than the average person, and no one is so low they deserve anything less than a good, comfortable life.
The changes to get from point A to point B are many and varied, things like employee tracking (looking at you Amazon), property taxes (remember when a home was something passed down like 15 generations? Yea, neither do I), and even the societal view as "work" as natural part of life have to go away completely. That's all extremely fucked up shit that too many people accept as normal and okay.
EDIT: I'm gonna stop here before my thoughts spiral out of control lol, I could probably fill a whole book w/ this dicourse, but I'm just kind of stream-of-consciousness-ing it rn.
