Drinking is a not a necessity. Comapring an expsnive part of Bangkok for rent is irrelevant when you look at the average rental costs in Thailand and oher areas of BKK.
Thailand is still super inexpensive. How many othr places in the world can you easily find rent for a clean and safe room for as little as 3,500 THB per month? Where else are you able to find a Condo for a little as 6k per month with security, swimming pools gyms etc?
Food is still super cheap- 40 -50 THB per meal to eat outside.. 3 of thsoe per day - 150 THB to eat well every day.. it's really nothing
Again, as i stated in my previous post, Thai people live wayyy above their means! No one ever put a gun to their head and told tem they have to take a loan out to buy a brand new car, buy the latst Iphone, or eat in Shabu Resturants 3 times per week...
