And yet, in another thread I made this exact point in relation to the question of why communism could never work and you disagreed then
In a system of true communism, you wouldn't need money to survive (as money wouldn't exist).
In our current system we live in, money is required (to purchase food/shelter) - we live in a "carrot/stick->reward" style system - not paying somebody for labour goes against the very nature of capitalism.
I can't believe I needed to explain that.
Human behaviour is based around what a society rewards, in capitalism money is a reward for work (which in turn is spent) - in a society without money the argument has no base in reality.
It's difficult to imagine, but our minds have changed in the last few hundred years - how our pathways are formed & the make-up of our brains changes to suit the society in which we live.
As we changed from hunter/gatherer society to an agrarian society our minds change to suit the environment - a combination of genetics, epigenetic's & environmental stimulus - this process does not stop.
(if you are unfamiliar with epigenetic's - a bit of info from Wiki on the subject pertinent to the point made)
Epigenetic features may play a role in short-term adaptation of species by allowing for reversible phenotype variability.
The modification of epigenetic features associated with a region of DNA allows organisms, on a multigenerational time scale, to switch between phenotypes that express and repress that particular gene.
When the DNA sequence of the region is not mutated, this change is reversible. It has also been speculated that organisms may take advantage of differential mutation rates associated with epigenetic features to control the mutation rates of particular genes.
Interestingly, recent analysis have suggested that members of the APOBEC/AID family of cytosine deaminases are capable of simultaneously mediating genetic and epigenetic inheritance using similar molecular mechanisms.
