Apperances, Are They Deceptive?

People judge others this is apparent everywhere in today's world. But are these appearances deceptive? The question is always met with the cliche response of "You can never judge a book by its cover." But even though this is a cliche it still holds some truth to it. There are people who look opposite from what they are. A great example would be my father's boss. He dresses normally and looks like anyone else. The catch is that he is rich, as rich as someone who owns a successful business can get. No one would be able to tell the difference if they had just met him.
We as a whole community base a lot of our opinons on first impressions. Apart from how they talk people look for how the other person presents him/herself. If the person looks crappy then most people would not want to talk to that person because of the  assumptions that are being made already.
Values are substantial in America for everyone. Everyone values a good society with swell living conditions as well as a good economic standard. They want people to look good period. When it comes to me I am split when dealing with significant others. It will appeal to me the most if the person I'm with looks good. But it could also be the exact opposite where looks don't mean anything an the person is great morally and mentally. Money is also a factor, not a really big factor but one nonetheless. If the significant other is not going to have or even able to get at least enough money to support half of the family then I lose interest. My values come first when thinking about anybody else. But even though my values are high, I can just as easily be deceived by appearances as anyone else. So appearances are deceiving most of the time.
