Quote from sle:
It's a truism. Any industry exists to enrich the business owners. However, if I were to ask you "what is the reason for existence of the tabloid press?" your answer surely would not be "to sell newspapers and generate cash".
The question O/P is asking is a good one - "what is the economic/societal justification for the existence of financial industry?". The answer to that is not as simple as most people would like.
Yes, that is what I was saying. Tabloid press does have a societal value, it provides entertainment to its readers.
