somerset well, yes, you do sound patronising lol.
I was making comparisons rather than giving examples from my life. Men in my life are absolutely, fine, thank you. To quote you...nice, kind, decent people.
And talking about nice, kind, decent people...what makes you think they don't go to strip clubs?
In my experience men don't tend to tell their significant others that they have been to a strip club. Precisely because they're scared of reactions.
So they keep it quiet.
In reality, most (not all, but most) men have at some point in their life been to a strip club...it's not all city bankers and builders, you know. I've danced for young and old, intellectual and not so intellectual, left wing and right wing, hipsters and geeks, university professors and manual workers, Muslim, Christian and atheist, liberals and not so liberals, etc...
ALL kinds of men go to strip club. Just because they don't talk about it (or even actively deny it) doesn't mean they don't go. 
If you think that it's just "less enlightened" men that go, you're very wrong. Or maybe all men are "less enlgihtened". 
Sure, things have moved on, but to me that means there's more choice than before. So whether you want to be fully covered in burqa or participate in naked dancing on stage, you have a choice to do so (plus infinite number of other options that fall somewhere in between). Isn't that a great thing?
You made a comparison with racist, homophobic, etc...attitudes of past, but you missed one component which means that the comparison is essentially flawed. It's not in anyone's genetic make up to be racist, homophobic, etc...Rather those attitudes were reflection of society's norms at the time.
When it comes to sex industry, it is in men's genetic make up to look at women, to be visually stimulated, etc...
It is because of that that sex industry always existed and always will.
There won't be a shift in attitude when it comes to that as it would mean totally changing men's genetic make up and that ain't gonna happen. What might happen is that the format sex industry takes changes and shifts to certain extent, but it will never be completely eradicated.

When it comes to dynamic between a dancer and customer, it's a bit of both. For sure, dancer is exploiting the gullible guy's wallet and the guy also gets the satisfaction of a pretty girl dancing naked for him. As for who is in control, in my experience, it's always the dancer. Guy's a bit helpless in all of that, to be honest. He just sits there and does what he's told.
As for the male dancers, I don't know if they have it easier, I don't know any so I can't really comment on that. I would imagine they would make less money than girl dancers as women would rather spend their money on a good pair of shoes than naked guys. The ones that do make good money are the ones that dance in gay clubs. It's mostly men that spend on sexual entertainment.
Candy Bar, again, I cannot comment as I haven't worked there.
And, yes, you are right, the whole thing moving underground would be the worst case scenario. The safety net that exists now would simply be removed. I mentioned "private parties" already where touching is the norm. If industry moves underground anything would go. There would be much worse working conditions, but people would still dance. Banning is not the answer at all, more and more uniform regulations are the way forward, not banning.

The argument that we all hear over and over again is that some women are trafficked. Well, here it is once and for all, that's a load of made up bull wheeled out at all occasions to make up the arguments for pushing the agenda of anti-dancing brigade forward. I have danced for years and in all kinds of places...I have NEVER in my entire dancing career met ANY girls that have been trafficked or coerced in any kind of way into doing what they're doing. You ask if the split is even. The fact is there's no split. ALL the girls are doing it willingly.
Just because someone is foreign doesn't automatically mean they have been trafficked and that they are somehow less capable of making perfectly valid choices with their life. In fact, it's terribly patronising to assume so.
The fact is that a lot of girls are perfectly comfortable with their bodies and they are happy to use them in order to make a decent living. But I guess that is a very hard pill to swallow for some so they have to make up trafficking stories.
Trafficking exists, but not in lap dancing clubs and pubs.
