I live here (Thailand) and do contract work at near western rates. That means I can live for months off the revenue from a single project.
To be fair though, the cost of living in Thailand is higher than the article makes out. Rent is quite high (if you want to live in a good location), and having western food all the time gets expensive. Expect to spend about 30k THB per month on ChefXP and FoodByPhone.
As for a variety of foods, Bangkok is hard to beat. Except for the lack of decent mexican food (Sunrise Taco should be burned down), we have pretty much anything you could want to eat... and it can be delivered to your door w/in 45minutes for less than you'd pay in the US.
Bangkok is a 24hr city. You can get good food any time day or night. There are always things to do no matter what the hour... ผมรักกรูงเทพฯมากๆเลย
I've lived on 4 continents (Africa, N. America, Europe, Asia), and I seriously believe that Thailand is the best country for living.
Living in BKK is another story, you can buy a decent house in a decent neighborhood for about 4 mil baht, which is cheap in my book. I have, due to the nature of my work, lived in nearby Salaya and commuted to shooting location and BKK with designated driver, prices of living there (only a 30 minute drive from BKK) are significantly lower than in BKK.
Also although the cost of living CAN be low, if you wanted to live cheaply and save money, you'd have to live like a middle class Thai person. That means no Starbucks (who the heck pays 80 Baht for coffee when you can get REAL thai iced coffee for 5 on the street). Even what we know as fast foods are somewhat middle/upper middle class.
The foreigners I know living in Thailand seem to live a pretty upper class lifestyle here in Thailand because their dollar goes a long way so I'm not sure how much they are saving. Then again, they're not hackers.
Even normal things that middle class westerners are used to could be considered luxury for the middle class Thai. Cable for example is pretty expensive compared to the cost of food and living and so is internet. Travel in the city can be dirt cheap if you stick to public transporation.
So again, you can stretch the dollar if you are willing to be fruga. Then again you can do the same if you choose to live in the states.
