Fair warning: OT from the OP
G.T.
At one point in human history we were required to hunt our own food in order to survive, we were also driven to procure a mate and reproduce. By the same token we were driven to "appear" better suited as a mate; this involved being better at hunting, having more fur, having a bigger tribe or harem, having a longer neck, or all manner of what people "at that time" and "in that particular area" found "attractive" and, oft, indicative of a more suitable mate. The underlying principle of this has never changed, however, the skills required to get them
have.
The past currency was just as "material" on the surface as "money" is today (though perhaps the drive for a "mate" has slightly shifted to being more of a "being successful" thread, in that today's society is not as reliant upon reproduction as in the past, when it was a matter of survival of the entire race.) We've both become more diverse in our modern "envy" of other humans; envious of their status and fame for example, and at the same time less diverse; as most of the things we currently envy happen to require money.
Of course humans would still innovate for ease with or without money, but that does not equate to ones life becoming any easier at all. It's no different then inventing the concept of throwing a spear rather than take more risks to stab the beast in melee... In the grander scope it does not change the 'fight' aspect; simply the skills to 'fight' are changed - one needs to become a better tracker of animals at which to throw said spear at for example - and especially as more rival hunters learn to also throw their spears. Or perhaps the short direct road humans are oft want to take; simply wipe out the competition for said hunting grounds/animals.
One can factitiously to boil it down to the modern concept of "money," but in doing so one is ignoring the underlayment of "human envy" that drives it all, and will ALWAYS drive it all - no matter what the "preferred currency of the moment" is. Which is ultimately the "fight" and "responsibility" I personally refer to, merely in a broader scope.
I am not successful simply because I learned to throw my spear, but because I did not stop "fighting" there; I continued to adapt in order to always be better then the rest of the hunters. Or in modern terms, I am not wealthy simply because I got a degree in computerized bookkeeping in 1993, but because I "continued" to push myself to learn all aspect of running a business, because I kept up with modern technology and deeper as a programmer, because I took psychology classes and management classes and customer service classes, and more - in short because I continued to "fight" to be the
best person for whatever job was necessary. I will never be "complacent" about my current state of existence, there is always "more" I can do to "better" myself.
