No. Thailand was recently ranked as one of the best health systems in the world. It has incredible private hospitals for those that can afford health insurance, and a good level of provision for those reliant on state aid. Compare that to France, which is reliant on sub saharan Africans with fake degrees and appalling hygiene, or the UK with 5 year waiting lists and diversity co-ordinators on 50k a year. There is no contest, Thai health system is far superior and well equipped to cope.
OK, so no proof.
