USE AND THROW

We use many materials now a days in our routine life, such as pen, pencil, rubber, gadgets, etc,....., all this things are useful for a certain period of time. For eg., pen is useful to us until it writes as soon as the ink in the pen is over will not write, a gadget, for eg., a cell phone, it is useful to us untill the features are new, as soon as a new version is available in the market the present one will become outdated.
All this things which becomes useless, we don't keep it with us, we just throw them in garbej or in a dustbin. Am I right my dear friends ?
But now a days one more thing is being used and thrown away and that are human beings, shoked ? It is true my dear friends, that now a days human beings are also been used and when  they are used totally they are thrown away.
Human beings are now a days used in many ways, they are used for a specific work. For eg., a contractor uses the worker for construction work, an industrialiast uses a worker for industrial work, etc., etc.,...... but friends here we talk about use and throw, so comming back to the point all this human beings which are at work, if they work for others personal interest and are given proper reward then they are not used and thrown in real sense. But if they are not given any reward and are simply removed and neglected then in real sense they are "USED AND THROWN".
Friends think and mark around you, the other ways where the human beings are "USED AND THROWN", as if they are of no use or they are equal to a "garbej" or "waste".
Friends, lastly I would like to ask u that if anybody helps you or does any work on behalf of you is it so they afterwards they are meant for "USE AND THROW" ?
