Money = Power. IOW power is an extension and function of money. If USA were not the richest nation on Earth in human history, it would have no technology or military, no power by which to make demands on (bully) others. It could then also have open borders without an immigrant problem.
Love of Money is the root of all evil, especially that of power. Power is the ultimate "thing" that money can buy.
