Are you still in high school?
Money rules the world. You’ll learn this as you mature.
No child, but you do seem to have a bizarre theory that history is over and the possibility of major wars has ended because someone recently invented money and economics.
People who truly mature gain humility as they realize that events often do not turn out as they thought. Money has tremendous power, that is undeniably true. But people don't always do as they're told, and paymasters are often mislead by their own vanity. There is nothing new under the sun, and human nature has not changed.
