Sorry but you're completely missing the point, to say it in a polite way. I don't understand why you have to make things look complicated, when they are not. The whole pseudo-analysis about currencies has nothing to do with saunas which are a local market.
You're very wrong if you think that garotos don't have "the capacity for broader perspective". You don't need a degree to understand that if gringos are stupid enough to pay much more than locals (and to get the exact same service, if not less)...they are the ones to go with. This is another reason why saunas are going to shut down as tomcal wrote in another thread. The local market is going to die because the locals won't be able to make it looking easily profitable anymore. No more locals, no more saunas. Internet is moving GPs out from saunas to apps like Grindr or away from Brazil (remember what happened in Cuba?). And "overpaying fools" are boosting this switch even because GPs in the internet know they can ask more money because their main target is going to be tourists. It's 2017...mass information. Garotos have friends around the world...they know how many tourists there are in Brazil, and they know how much these tourists pay in their homeland, and they know that tourists prefer internet dating. We, people on this forum, represent a painful minority for saunas owners.
Everyone is free to do think and do whatever it wants to do. But please, no bullshit. I will not filter GPs thoughts, because i would lie. GPs will love you and will be interested in you until you pay them AND until you respect them. It is all a fake.
There might be some rare exceptions but you're just the ATM from where they can withdraw cash money.
Everyone is free to live in wonderland.
I know at least 2 friends who overpay GPs....one from Europe and one from the US. Can someone tell me why, while they like to overpay GPs (R$250/300...which are around 80/90 EUR/USD), they get mad at the idea of tipping 1 penny to a NYC escort who asked them 400 USD or 200€ in Paris?
I will tell you...because they have problems with their egos, and that's why GPs laugh behind them.
