"Money changes all the iron rules into rubber bands"

This quote suggests that money has the power to bend and flex guidelines that are normally stiff and inflexible. It suggests that when monetary gain is at stake, people may be most likely to jeopardize their beliefs and worths in order to accomplish their wanted outcome. "Iron guidelines" represent authoritative guidelines that are normally non-negotiable, while "rubber bands" are flexible and can be extended and adjusted to fit different scenarios. Therefore, the quote implies that cash can turn what was when seen as unyielding and undaunted into something that can be controlled and altered to match personal or monetary gain. Eventually, this suggests that cash, for better or for worse, can be a transformative force that can change the very nature of societal guidelines and expectations.
