The text is a play on the phrase 'Golden Rule', which traditionally refers to the principle of treating others as one wants to be treated. However, it humorously twists the meaning to suggest that in reality, the person with the money ('gold') has the power to 'make the rules'. This creates a pun by juxtaposing the ethical maxim with a cynical observation about power and wealth.
Golden Rule : He who has the gold makes the rules .
