Article seems like clickbait. The rents are cheaper and at least you have the option to live in a great place for under 600 a month if you really wanted to economize and pay down falang-land debt.
As far as a long term solution...options seem limited and expensive with quite a bit of administrative processing. Remote work is subject to taxation and that's if they don't hassle you for not having a work permit so not sure how it was voted a great place to work.
Groceries are a little bit cheaper. You can't exist on street food unless your diet has been <deleted> your entire life. Then it's just a transition from garbage western food to garbage thai food.
On average ordering a grab meal for myself daily runs anywhere from 250 - 350 baht depending on the restaurant and 400-600 for dinner when I order for my wife and I.
I will say this tho...as far as things to do it's great. Love visiting new cafes, lounges, and restaurants every weekend. Love being able to get out to a beer garden and revert to year 1 - 3 living for a night. Makes me remember all the reasons I fell in love with this place. Now that we have legal weed I have pretty much everything from my falang life here at a reduced cost.
