Your post is either a troll, or you're being completely ignorant of the reality of how things work here. Maybe you're a newcomer.
First of all, you have to realize that most women open to date foreigners or 'farangs" are the girls that Thais don't want or are not attracting to anymore. Reason may be because they have darker skin, they have bigger shapes, they have a lot of tattoos or they have a child already. Thats it. So the 'hot, westernized' type of type girls you bang as a foreigner are the girls Thais don't want, and the girls know that. That's why they chose to actively date foreigners only.
Those girls are also a very limited pool as well, constently dating the same transient foreigners and sometimes having several "sponsors" or daddies that fund their vaping lifestyles.
The second thing is that most people date inside their social circle and inside their own kind. Majority of Thais date Thais. That's it. There's no workaround around it. Sure, you might have the odd one 'trying out' a farang, but most Thais will always want Thai for obvious reasons (language, culture, etc...). Then you have like I said the limited pool of Thai girls who go for farangs only. And even then, in 2024, Western foreigners are in fierce competition with Koreans, Chinese and Japanese. Lots of Thai girls would prefer a handsome rich oppa rather than a broke Westerner that doesn't know how to dress and who smells bad.The paradigm has shifted in recent years.
Then, you say foreigners are taller, more handsome etc... than Thais. Where did you get this idea or why do you think being taller instantaneously means you're more attractive? You might be a novelty for a while but... you know, every white foreigner is handsum here. Almost every time i go out, someone will tell me 'you so handsome!' Learn to deal with it. It doesn't mean anything here.
Foreigners are not being perceived as 'more handsome' in the sense that you think, trust me. Thais are very popular as well. Look at the advertisement. Do you see any white guy? No. It's all white skinned Koreans or Chinese. That's the model. Foreigners have more money? Some do, for sure. Some have better wages than Thai people, overall. But do you want to be seen as a walking wallet?
