Footnote.
*We have in the history example of people who have selflessly helped others to progress in life*. One such spectacular example is of India’s living legendary singer Dr. K J Jesusdas (who was disfellowshed from Catholic Church for singing devotional songs of other religions—an act that led him into Hinduism http://www.drkjyesudas.com/). His message is his life. His father died leaving him only financial liabilities. When he wanted to learn classical music, and sought financial help from his Diocesan Bishop, he was sent back in ridicule. But he came up in life by his own effort, and became almost like an Emperor among singers in India. He was being given all the awards for the best singers, finally he decided not to accept any awards from any organization so that others receive them. Now he even decided to stay away from singing for films so that new comers would have opportunities.
Now something in particular. When he became very busy, all his studio recordings were done without him, but with his part being sung by a substitute (track singer). Then later, Jesusdas would come and sing, and replace the portion sung by the substitute. In the final mixing, it will look as if it was sung with all the orchestra at the same time! One day when he heard the recording of the song sung by the substitute, he found it was perfect., and requested the Film Director to accept that song sung by the substitute for the film, which gave rise to another famous singer Mr. Unni Menon (http://www.unnimenonsinger.com/).
