So, about a million baht a year brought in to Thailand. And then it is all spent here. I am thinking that tax is collected on all sales … including the gas for the car and motorbike, which also bring to mind the registration tax. As a U.S. citizen, I am not going to worry until I have something to worry about. Worse comes to worse? I am free to seek retirement elsewhere, perhaps where I am allowed to join the national healthcare scheme.
