During wars, the central bankers CREATE fiat money and credit from thin air. They lend out this artificial money and people buy incredible amounts of war supplies. The taxpayers get stuck with the bill. It's a mini-boom that DROPS living standards for all but the war-profiteers. The middle class gets smashed with debt and the central bankders end up owning more and more. It is a very old racket, and there's a reason why these bankers buy up all the newspapers and media historically. They spin all sorts of nonsense to distract the people from what the crooked pols and banker cronies are actually doing.
Tactic #1 is to split up the public into two parties that hate each other. That keeps the focus on the other party.
