it's a statement not an argument: two people can have the opposite believes and both can be right. Whatever one believes is right to them, therefore everyone is right.
I know two business competitors who have completely different philosophies, opposite work ethics, one borrows while the other pays cash, they have opposing management techniques, and they don't like one another, yet both are very successful in that they have built sustainable enterprises that produce income decade in decade out. Each thinks the other is wrong and will take that belief to the grave. Clearly though they are both right in that their way is the best way to run a business for them. And clearly they are both wrong because they see the other one as wrong.
Your observation was interesting about the rulers etc. I like being in the middle myself. neither a ruler or a follower be.
But this is a trading blog not a philosophy blog. I don't know if I'm right or wrong but I will continue to sell rallies in the Euro.
