Money was invented by man for man
Money is / was intended as a universal medium of exchange to replace a very complex barter system
Actually, many different media of exchange have been used, none universally. Barter systems of various kinds worked quite well for most societies.
Shells and other kinds of [durable, portable, recognizable, countable] coinage were employed long before the first official coins were minted.
The main point of currency is for the ruler(s) to be able to 1. set a standard value 2. limit the amount of currency in circulation and *3* collect taxes in a convenient form.
Instead of goods of all sorts being exchanged a barter became between the goods and money
Wealth is a value judgement and really is unconnected with money
The standard value of money is set by the rulers who coin a currency; it connects to whatever can be bought and sold.
The absolute standard of wealth in most societies, even to the present time, is land, but other lasting properties, such as fresh water, lumber, metal ores,fisheries
energy, human and natural resources, comprise the total wealth of both individuals and nations.
Wealth is a measure of the amount of goods and services one owns/controls/commands; money is
a unit of measurement.
While goods of many kinds can be accumulated, stored and passed on from generation to generation, time and effort cannot.
But time and effort - and human beings -
can be owned and evaluated in terms of money.
It, wealth, as a value judgement is neutral as to benefits
The other way around. That which is beneficial (like seasonal rain to a good harvest) adds to wealth; that which is harmful (such as a late hale-storm) detracts from wealth.
For example, if Tribe W controls fertile acreage, a riverfront and a forest with walnut and beech stands, it is richer than Tribe P, that controls arid hills.
The P have only sheep to exchange for W's fish, nuts and yams, which they need, while the W have no great need of mutton and can manage without wool.
However, the W may be short of manpower to till their fields and haul in the nets, and so the P may hire out their labour.
Or the P may discover tin and copper in those hills and become forgers of metal tools, which have a far higher trade value than perishables,
and so the P may, over a few decades, grow richer than the W.
Wealth is relative, but never value-neutral.
I presume this refers to the valuation of citizens.
Of any given society, that valuation is knowable and measurable in at least three different ways. One is the distribution of wealth,
but the more reliable are standard of social welfare (health/longevity; contentment/accord) and the system of laws.
My questions were aimed at trying to establish the role money does play and should play in the life of a society.
It's impossible to discuss wealth meaningfully if money is the standard, since money is not only valued arbitrarily,
but is the quintessential medium of skewing relationships, economies, political function, social organization and the allocation of resources.
The great leveller of wealth is social collapse, when currency, stocks and deeds become scrap paper,
and there is no legal enforcement of ownership or rights. Then a nation has to start again, in something like equality -
how well it distributes the available resources then depends on its human values.
