Anonieme deelnemer 988 spending money is indeed also paying tax, but with only 7 percent it does not make you a substantial tax payer, so I agree with you spending only a little amount of 50k or 60k a month is no excuse for not paying tax.
DTA then decides, some income might go to one country and other income to the other country, also income taxed at both countries is possible, but nomally not above the country with the highest tax. It can be very complicated.
I disagree with that filling in gaps is evolution, but when you want to call it that, just do.
And indeed Thai embassies have a lot of freedom to decide, but it might be obvious that for learning the language the ED visa is already existing a very long time.
I not say embassies that accept are wrong, I only say for learning language there is another visa, so embassies mighjt reject DTV because there is a more suitable visa.
Now some language schools might also want to profit from the DTV hype, and then they try to combine language learning with some cultural elements
