This poem is sometimes described as inspirational. I'm not sure it was meant to be. To me it draws attention to some hard realities of life without acknowledging that they are just. Something of a criticism of mankind and society. Complaining about these realities would be to contravene the message of the poem!
'If' by Rudyard Kipling
If you can keep your head when all about you
If you can dream - and not make dreams your master,
If you can make one heap of all your winnings
If you can talk with crowds and keep your virtue,
Part of this is a pretty good description of how I remember my working life at Marconi Defence Systems and elsewhere, where I had to put up with gross injustice, but if I complained it was counted as further criticism of me.

Funnily enough, Jesus said something which I can recognise as similar. There was a story where some workers arrived for work at the end of the day, but still got paid the same as those who had been there all day. Jesus said the workers who had been there all day should not complain, because they still got paid in full, and the payment to the latecomers had no effect on their remuneration. Well I'm not so sure.
What about fairness, justice. Shouldn't we all strive for it?
