I think Thailand as a destination for new retirees will be significantly reduced in the future. Thailand is not easy nor cheap anymore. People who go online and search for 'retirement in Thailand' will be flooded with pages full of negativity, talk about scams, racism, visa issues, and be immediately turned off. When searching for 'value' for money, Thailand doesn't even make the top retirement destination lists as it used to pre-2014. With that, I struggle to see a business case for attracting new retirees to Thailand that aren't looking primarily for the girls. But even that scene I think will be less in your face and instead move online in the future.
This entire pandemic has been a stake in the heart for Thailand as far as I'm concerned. I don't see any possible scenario where they come out of this with anything near what they had before.
