"Sinners"? What the hell are you talking about?
Are these people, who are dancing in the stage, entertaining those who are thirsty with sexual needs can be tagged as sinners?
For me, not. They are one of the victims of this society full of capitalists. Who among you would have the guts or will attempt to enter this kind of job, lower down your dignity and make your tummy stronger to swallow what the costumers demand you to do just to have a scratch to feed yourself, if you can get a more decent job? But how can you even get a good one, if some (if not many) of the local employers would rather give the opportunity to the foreigners as if their fellow Filipino can't do the job? If there's an instance that they would give it to a Filipino, it will be surely contractual. Isn't it a shame for a country, with a high unemployment rate and had thousands of overseas Filipino workers scattered around the globe, to accept foreign workers instead of having their fellow Filipinos?
It's the call of the stomach which needs a food to grind.
Also, is there will be place like this kind of bar (not all bars) if none would have the idea to build one? Is there will be places like these, if there's no demand for it? If there's no costumers who will patronize it? Who among the characters of this setting, every night, used to touch the sensitive body parts of the entertainers and invite them for a good one-night stand? Who are the one who's taking the weakness of these workers (which is money) as an opportunity for them to feed their ego, for them to feel their worth and for them to experience temporary love after having a relationship which didn't met their expectations?
You don’t want to see these scenarios? Then think! If you are an employer, are you one of those who have high standards? if yes, now lower your standards. Are you one of those who patronizes IMPORTED/Foreign PRODUCTS AND SERVICES which dominates than the local ones that causes these local enterprises to close (if not made an retrenchment) and left it’s workers unemployed? Then change your perception now. Change your choices. What do you want, these unemployed people just let themselves die in hunger? Of course, they will grab the job offer, even if they will need to lower down their dignity as an exchange. Logically, can they eat that dignity? Of course not.
And then, you would hear people, mocking entertainers and making laugh at their occupation. Hypocrites, who are the sinners again?
