This is noteworthy, no matter how much material advantages you pump into a system to blind and bend it your way, there is a verse in the Bible that says “I have 7000 men that have not bowed to Baal” that incorruptible conscious minority is always enough to change the game.
A system is never completely corrupt or else it would have totally collapsed. There are always a few individuals within it that may not be vocal or visible but are strategically placed such that when prayers are offered, God can through them pull triggers that will cause the entire plan to fall like a pack of cards.
God remains on the throne and He still rules in the affairs of men. There is a God-factor in our national polity, he only needs his own to offer up prayers and the unexpected will show up before our eyes.
