There is an evil I have seen under the sun, the sort of error that arises from a ruler: Fools are put in many high positions, while the rich occupy the low ones. I have seen slaves on horseback while princes go on foot like slaves.
The problem with the rulers of this world, is that they put fools in places of authority. These fools have big ideas of their own instead of the wisdom that is from God. The rich that he speaks of is those who have the things of God in their hearts and minds. Have you noticed how those that are serving the Lord (princes) have to walk along as the poor in this world? Just look at any ministry that is following the Word of God and you will see that they do not live the high life.
