This is a thread I have wanted to post for a while now, and today it is raining very hard so here it is.I want to see the opinions of you out there that know times in the past where you could do something, but someone else could not, and it was because you were stronger. This will require the limits of work only, and this can be anywhere, home ,office, or farm. Now let us move on with the question and refine it. Let us say you could do it , but someone else could not and now for that person to do it , a costly machine was added so they could do what you do.I will give just one examle, but I have many.I have two workers, one weighs 250, is 6' 8", and very young.The other is 5'6" and weighs 120, and 44 years old.The first person can move aluminum coils of tubing by hand, carry them, and put them into a machine. The other person required a very large movable crane to be installed just to do the lifting.O.K. this is the the main question:From a managers point of veiw(and I am not)would it not be more productive and cost efficient to let certain physically typed people do certain things (if they are faster, and save money)or install costly machine to processes to let anyone do it , even if it is slower-not safer, just slower? This is all based on a theory I have that human labor is very seldom ever used efficiently, we too often want everything to be generic, and this is so off base it defies even the rules of nature. I mean think about this ... this would mean Lions could fly, and Rabbits would prowl the Savannahs hunting Zebra. I know we are Gods children, and not animals, but even the creator endowed each of us with unique and special gifts.Marty.
