In terms of trade, it is possible to define money as the commodity can replace any other because with it we can cancel any exchange.
In other words, being that the sale is a form of barter, money is a commodity, just regulating their quantity, can be equivalent to any other commodity for which we want to swap. For example, both can exchange money by a goat, for a building, for a trip.
If we see the opposite, both a goat, as a building, like a trip, are equal to each other because, in turn, can be exchanged for the same commodity: money.
When that money is meant to be swapped for the work of a worker, that is, when that money functions as salary, we also found a phenomenon of equalization among workers because everyone can produce the same commodity exchange payment: the money. In any case, as in the purchase and sale referred to above, the difference will be given in the amount of money, as some workers are paid more than others.
Humans struggle to have their own identity, we need to be holders of traits that identify us clearly, such as names, IDs, nicknames, photography, profession, socio- economic class, number of children, vehicle. Everyone wants to be different from others.
Hypothesis: Some people with pathological poverty unconsciously may repudiate the money because this is a commodity that equates with others. Since all our work permute the same ( salary, fees ), it is possible that some feel a limbo loss of identity, may feel lost, dissolved in the human mass, smudged, no limits, no body.
Note: Original in Spanish (without translation by Google): El dinero nos quita identidad.
