The Thai economy is loosely based on the Taiwan model. As such, it is dominated by the plucky proprietors of small and medium-size enterprises, who will not countenance a government flunky telling them what to do. This is quite at odds with the South Korean model, where a chaebol boss may wait days to meet the bureaucrat who can tell him whether to make more red cars. In theory, the Thai system is flexible enough to adapt. You won't find it in South Korea or Singapore.
Market forces know better.
We do not want to pick winners. We will make mistakes if we start picking winners. While Malaysia and Singapore are turning away labor-intensive industries, Thailand makes no such exclusions. If you think you can make money while others are losing, good luck to you. Maybe you know something others don't.
