The same here. I contribute to the Thai economy, support a few good businesses with my custom and tip good service. However, the charity and social support can be left for the Thais to do.
The regime doesn't seem very good at that, but it's an issue for Thais to fix, not me. They seem quite good at channeling money towards all sorts of crazy schemes, including keeping certain individuals in extreme luxury, shoddy and pointless construction schemes, subsidizing diesel and even funding the detention of people who fail COVID tests.
Incidentally, quite a high proportion of my holiday expenditure ends up in the hands of Cambodian and Lao citizens. So that's going to the even more needy.
