I don't believe the amount of money a person makes or their education level has anything to do with respect.
Some of the greatest men in history have had little "traditional" education.
Albert Einstein, for example. Who doesn't respect him?
Society puts so much pressure on men to be the "bread winner" and to support himself and his family that it becomes tied into his identity. He is conditioned to believe that if he doesn't make more, then he, as a person, is less. This is sad.
There is so much more to a man than his educational and monetary "value".
In fact, it is the rest of him that makes him worthy of respect:
His heart, his compassion, his integrity, his drive... His ability to love, to make you laugh when you want to cry, his inner strength, and his moral fiber.
So, yes, I can and do respect men who earn less and who are less educated than myself.
