To do so indicates we are subjects, not equals. Heads of state should be considered equals.

God money I’ll do anything for you.
God money just tell me what you want me to.
God money nail me up against the wall.
God money don’t want everything he wants it all.

Bow down before the one you serve.
You’re going to get what you deserve.
WELL PUT.
