It's hard to ignore hard data.
I've talked to many intelligent men, who have an excuse for every individual "item" with the sub-total being "I don't have to change my life or worry -- everything is fine."

Perhaps the secret is to be able to "put it all together" and see the big picture.
Anyhow, let's see anyone claim that everything is fine, when the US Dollar is doing this:
