That's the stereotype from one whose activities are purely for sex. But it's simply not true in some cases. I know of three couples where the Thais have university degrees and business ventures which give them a greater income than the farang. Keep an open mind. And don't rule out the apps but be very selective. Remember, too, that Thailand remains difficult for many younger Thai business professionals. It they work for a company, the vast majority will not want their colleagues to know they are gay. That can lead to discrimination including lack of promotion possibilities. It's one reason you will not find more than a few Thai professionals in the western gay venues. They will go to the mixed gay/straight bars and clubs around Soi Thoonglor which have gay sections.
