I feel as if both forms of measurement are social constructions. Time is relative in the sense that it differs for every person. Technically, when your time ends, your time ends. When your time began, your time began, and nothing existed to you, until you were socialized into understanding this world and how to interpret it.
Take Tupac and WEB DuBois for example. We measure other peoples notions of time against the average of our own notion and the notion of others, but when you die, your time is up, technically hasn't everyone lived a full life? Time is distributed unfairly, with people like Stalin living to an old age, and Fred Hampton dying in his relative youth.
Everything else that is non biological is based on a social construction. There are many different calendars in both the present and the past cultures. We measure time by the moon, menstral cycles, seasons, clocks, life span, the sun,
We base to much of ourselves on the notion of time, and in consequence, we forget about how to live in the moment. And if I had the opportunity, I would take the time, because when you take every day, no matter how you measure days and time, for what it is, and embrace the essence of the moment, you live.
Money goes hand in hand with oppression. Eventually, we will have to evolve to a new social constuction to ditribute privilege, but for right now money is the tool.
