Earlier quoted context omitted.
Providing enough for everyone to exist is trivial, what's distinctly non-trivial is satisfying those needs in an economic system like ours. Right now our economy requires access to necessities to be precarious, to motivate people to sell their time and most of their freedom to Those In Charge to buy them. The alternative to this, where everyone has what they need to exist without submitting to one leader or another,…
The only reason we have enough is because of that economic system. Take a look at Venezuela. It ought to terrify everyone that so many take what we have for granted.
Iain Banks puts it nicely in his "A Few Notes on the Culture" essay [0]:
"Let me state here a personal conviction that appears, right now, to be profoundly unfashionable; which is that a planned economy can be more productive - and more morally desirable - than one left to market forces.
"The market is a good example of evolution in action; the try-everything-and-see-what- -works approach. This might provide a perfectly morally satisfactory resource-management system so long as there was absolutely no question of any sentient creature ever being treated purely as one of those resources. The market, for all its (profoundly inelegant) complexities, remains a crude and essentially blind system, and is - without the sort of drastic amendments liable to cripple the economic efficacy which is its greatest claimed asset - intrinsically incapable of distinguishing between simple non-use of matter resulting from processal superfluity and the acute, prolonged and wide-spread suffering of conscious beings.
"It is, arguably, in the elevation of this profoundly mechanistic (and in that sense perversely innocent) system to a position above all other moral, philosophical and political values and considerations that humankind displays most convincingly both its present intellectual [immaturity and] - through grossly pursued selfishness rather than the applied hatred of others - a kind of synthetic evil.
"Intelligence, which is capable of looking farther ahead than the next aggressive mutation, can set up long-term aims and work towards them; the same amount of raw invention that bursts in all directions from the market can be - to some degree - channelled and directed, so that while the market merely shines (and the feudal gutters), the planned lases, reaching out coherently and efficiently towards agreed-on goals. What is vital for such a scheme, however, and what was always missing in the planned economies of our world's experience, is the continual, intimate and decisive participation of the mass of the citizenry in determining these goals, and designing as well as implementing the plans which should lead towards them.
Of course, there is a place for serendipity and chance in any sensibly envisaged plan, and the degree to which this would affect the higher functions of a democratically designed economy would be one of the most important parameters to be set... but just as the information we have stored in our libraries and institutions has undeniably outgrown (if not outweighed) that resident in our genes, and just as we may, within a century of the invention of electronics, duplicate - through machine sentience - a process which evolution took billions of years to achieve, so we shall one day abandon the grossly targeted vagaries of the market for the precision creation of the planned economy."
