I believe it was John Locke who once made a very good argument for defining Property as that which is obtained by labor. I was thinking maybe this would be a good idea. When you think about an equal society, rather than using a monetary coin or paper to define income and worth to obtain property, perhaps we should literally use labor. I believe that in an equal society, the best person for the job should be selected, but his time in that job is equal in value to the same time spent by another individual in another job. Essentially what this boils down to is one hour's labor from one individual is considered equally valuable to one hour labor from another individual. If it takes four hours to make a single unit of an item(eg, a TV), it should cost four hours to obtain, own, or have as personal property. One might think "But hey, if everyone's time is equal, noone will get ahead!". However, one can easily get ahead by saving time spent; if you only spend half of the hours you accrue, you will build them up over time and be able to make large purchases. The secret to making this system work overall is in how you consider education valuable. Instead of making it more valuable on the time side, we can consider the time spent obtaining education itself valuable. You are paid an equal amount as you study; a portion is removed to pay the cost of education, and the other available portion accrues into a bank which you can either spend or save. After 8 years of education, one might accrue a large pool of funds to be put forward to the purchases required to go into business(labor cost of maintaining material farm, labor cost of processing materials to parts, labor cost of delivering parts to location, labor cost of assembling parts, employees). We already track worked hours to determine pay, so the information is already collected and available; private property is still available, and contains all items which could be considered luxury items(not absolutely necessary for survival). If it takes 1 person 1 hour to make, it is worth 1 hour at sale. If it takes 5 people 5 hours to make, it is worth 25 hours at sale. To make such a system work, we need locational housing(we have hotels) for the individuals moving around to different jobs that they are best suited for, we need a system of tracking time spent working(we have timecards and digital tracking systems), and a system to track account balances(we'd have that still whether we let the banks die or not). This "currency" is universal around the world, and any Country that's interested or willing may join into it. It's not quite Capitalism, because in this system, noone is attempting to "Capitalize" on the transacation; just earn their fair due for their work or studies. "Taxes" are instead hours "gained" by the government through willfull donation of time; certain assignments are issued by the government, be they for research, manufacturing, or construction work. Time spent is divided amongst government(unified spending body) and the individual(denominative spending body). Government funds are used to pay for the hours spent by the other people earning that portion, and are used to pay for whatever cost the societal body incurs; be it for group-shared things like arenas or for public amenities. These costs can also be partially paid for by willfull donation of hours from any individual, private or public interested in putting forth currency to gain the benefit of the grouped "large purchase". The relative values stay the same overall, but there is less ambiguity, and less erratic motion in the system. A TV might cost 4 hours, a car might cost 50, a stadium might cost 10,000. They are proportionate to their time required to create, rather than the desire to profit on the transaction. Just a thought.
