What's your problem man?Which part can't you understand?Do you have problem with it's grammar or just can't understand the meaning? I think you mean the quote from Titanic,ha? It says that the money is useless for both of them in that situation.It can save none of them.

a) we are all below the same sky. b) money and health are unrelated (to be precise, by health I mean the possibility of contracting or stay away from illness, as the possibility to cure it is another matter).

This quote is from the film Titanic. It means that rich people who were passengers on the ship were just as likely to drown as poorer passengers and that their money was no use in such a tragic situation.
