Nightclubs definitely take advantage of this concept though and the OP is not wrong. Just about every big nightclub venue will have an instagram account as an advertising tool. They very often will take pictures of a variety of attractive women, those that are customers and those working there, to help lure in men. Men show up hoping they can meet a hottie but by being there they are paying the cover charge and for food and beverage. Another trend I've noticed a lot is many nightclub venues will hire attractive women as bartenders and servers but for their uniform they are in lingerie, etc. Again, this is just to attract men to the establishment to make money.
With all of this out of the way, the male to female ratio at any bar or club is definitely not 1:1 lol. I don't have exact numbers obviously, but from the start the numbers are not in a man's favor. Nightclubs really aren't a great place to meet women due to a variety of factors, this just happens to be one of them.
Maybe so. Nightclubs exist to make money, not to get you laid. Nobody forces anybody to spend their time and money there. Women are everywhere. Nothing is "rigged," it just is the way it is because different entities have different objectives.
The problem isn't them, it's the man for being thirsty and believing the advertising. They put women in beer commercials, too. Nobody ever went broke promising p*ssy.
I know the OP said it wasn't a rant so not flaming him. I guess my point is it's not a fix. If clubs could, they'd fill the place with women. It's just the law of the jungle, men will flock to chicks. Like when you see a cute girl at a table with multiple guys. Or dudes liking female social posts en masse.
For my part, I just ignore the noise and soldier on. I'm my own man and don't get sucked into groups or crowds much, even in social settings.
