Some years ago I was talking to a (younger than me) British guy. He was planning on moving to Spain with his Thai wife & kids, he said he was paying around £100 per week for his 2 kids to go to (primary) school in Thailand.
I also knew many retirees who left Thailand due to medical expenses, 2 guys I know currently have left Thailand for cancer treatment. One old guy I know had successful cancer treatment at B'grad, it cost around £40k, but he's a millionaire. Another (very wealthy) Swedish guy, a good friend, ended-up parting with around 5 million Baht (B'grad), before eventually going home to die in Sweden.
(These are all things that people get for free when they move to the UK, unsurprisingly we have massive queues for healthcare).
