How are strip clubs demeaning to women?

Now this is obviously coming from a guys perspective. Personally I do not see how strip club are demeaning to women. I've known a few strippers outside the strip club I didn't know they were strippers until they told me. They said they made about 300-500 a night which means there getting a lot of money for dancing and showing the parts guys love to see on a women. If anything these women are taking advantage of guys lust. Seriously of all had to do was show my dick do you make 300 to 500 bucks a night I'd do i I'm not gay and don't have a 6pack so couldn't do it. But yea someone please explain this logic to me?
