Note: I'm talking about my PUA friends, I used to practice PUA but left it. Since the more I got into it the more I found it less appealing. I notice that a lot of people, including Roosh have made this connection. Also, I noticed that they are not only similar to strippers but also SWs like cam girls..etc.
There are way too many similarities but here's a list: 1-PUA's are interested in having sex for free, Strippers want to get money without having sex. 2-PUA's will talk to women they don't like just to have a chance at sex, strippers will talk to men they don't like just to have a chance to get money. 3-PUA's will get unattractive women to have sex with them, strippers will get unattractive me to give them money for dances or maybe OTC. 4-Some PUA's do not like the women they are talking to and some of them are openly misogynists. Some strippers do no like the men they are talking to and will thrash talk them behind their backs. 5-Some PUA's will go with their wingmen and pretend to be gay to get a women's attention, some strippers will kiss female customers to get their attention. 6-Some PUA's are so misogynistic that they'll delve into bisexuality..etc(I didn't know this but I have now realized it). Some strippers/sex workers are also liking to do girl-girl only content for only fans..etc. 7-PUAs see themselves as the product and want to be the desire and wanted, some strippers also see themselves as products to be desired and wanted. 8-Some PUA's see it as their job to interact with women. They'll approach girls even in their off-hours. Some strippers also see it as their job to interact with customers. 9-Many PUA's are cheap and don't want to spend any money, similar to strippers and even sugar babies. 10- PUA's will go to seedy bars to target the less attractive women, strippers will go to clubs to attract the less attractive men. 11-The ratio in the bars PUA's go-to is usually 8 men for 2 women, therefore, the whole practice is very competitive. Some strippers friends told me that they see the other girls are their competition. 12- Strippers go for the men with resources(say 20%) who want to invest in them. Meanwhile, PUA's do not want to share their resources with women and in theory, want only to have sex and leave. 13- Some PUA's want to become gigolos or even male strippers since their goal is make money. And the list could go on and on.
Overall, I think guys who become John's/Tricks prioritize having sex and like women. Meanwhile, guys who become PUA's want either emotional validation or money. Eventually, a lot of guys who end up doing PUA becoming coaches themselves. As PUA coaches they focus on "gaming" their students to make them spend $1k to $10k on their "self-help" programs.


I've posted this elsewhere, but a very good friend is a top copywriter who used to run in those circles. He's on a first name basis with a lot of the big names.
Maybe they are like strippers, the lower end of the bunch.
