why do people consider the willing as granted ???

this question had always haunted me , and often i have self replied to it as " neki kar kuein main daal " .
Maybe i have been wrong in this regard as today the times have changed and the present generatoon (generation) does not respect such thoughts and views. . .
Our generatoon or today even i can be regarded as an oldy, having passed my 26th last week, the present lot has taken the thought that everyone does something for a reason,
selflessness does not strive in today's materialistic society !!!!
