Not to pop all of your predictable conspiracy bubbles, but of the last 6-8 months there have been some quite extensive and legitimate scientific research and studies from well respected figures in their fields as regards to COVID origins.......all have concluded that this bug, like many others, derives from nature - passing species to species in one form or another.
Naturally, this work and material [all quite publicly available] was/is almost always ignored by the Western convention - in particular the English-speaking variety.
But what you're simply saying simply isn't true.
As you've been shown, repeatedly, those on identical visas in Western countries are either given identical treatment and charged the full price for medical treatment, for example in Australia, or charged 50% more in England.
If you disagree, give an example of those on the same visa in any Western country where Thais get better treatment, with some evidence.
But most Western countries don't give those who retire there any "status " at all as they don't have retirement visas or visa extensions for retirement - and the "status" of those who "marry one of their nationals" is seldom any better, generally with no right of residence or with much higher income requirements for residence so worse, and with similar requirements for residency or nationality.
If you disagree, name any where the "status" is any better, with some evidence.
What "irritation" is the case causing?
The case has had minimal interest anywhere except in local expat news.
It would be nice, but from a Thai perspective - why?
Thai retirees in the West are either treated similarly or not allowed at all, so there's no reciprocity, and it would be unlikely to encourage any more to retire here apart from the freeloaders who contribute nothing.
So - why?
For once we're in agreement - but I'd include all the Western countries that also have similar dual pricing - some far worse - which you've ignored, which will also not change anything.
Feel free to respond to anything, with some verifiable evidence - or, as usual, to find an excuse not to.
