Work equals distance by time in one sense in an ideal world view situation. Makes no accounting of resistance to the force or the will of that man to work especially in the state of futility. That one is propagated by the state from birth to death to pay rent, bills and taxes to end up with a legacy that is inherited by the next generation of plebs. Once we travelled on wilderness tracks now we travel across the world at the speed of light. National boundaries dissolved into thin air. Where is my paycheck for services rendered to that community? Where is that community when the neighbors do not want to talk to you because you are not a member of their club and its conspiracy to defraud its members with lies about our origin when all you have to wear is old smelly socks and clothes. A lot of work has been done by mostly slave labor for the living standards those of the western hemisphere take for granted. SI units is but one of those lists of standards. An ever present list of units the vast majority take for granted.
