Thailand is cheap compared to the west and will continue to be for many years IMHO .
I agree with the comment on the photo . Bad choice .
Need 100 k of what ? If you mean US dollars very few foreigners living in Thailand would have that much money available . A place to retreat would be ideal ,but i do not believe there would be many that have that luxury .
I am not sure of the percentage of foreigners with health insurance . I would say about the same number of foreigners living in Thailand with 100 k in the bank and a place to retreat .
I have patience for all people that do not interfere with my life . If a person chooses to live here with no insurance , no money in the bank , no escape plan then that is up to them
