Question

what does it mean by 'a dollar earned is of far more value than five pound'

Answer 1

This is an interesting question.

This means that the money we get from doing hard work makes us feel happier than money which we steal.

Always try to work hard.  Earn money by yourself instead of snatching from others.  It will give you happiness and self- satisfaction.

The money which we earn by own self- fulfill our needs as well as our wishes.  On the other hand, the money which we steal might fulfill our needs but not our wishes and self- satisfaction.

Hope this will help you.

Answer 2

This means that a dollar which we earn with hard work is more valuable than the money that we get by stealing.
