More nonsense from you,
The high tech aspect is that in a modern volunteer army soldiers have the opportunity to learn a trade and acquire expertise that will be useful in future civilian life.
There is no need for the army to introduce rural people to urban people.This might have been the case in the 1950's which seems to be your mindset period. However the economic transformation of Thailand since then means that there is a constant flow of people into Bangkok and big cities. The army has no role as a socialization tool, whatever that is meant to mean.
You skim over the reality that the Thai army's purpose is to make money for its senior officers.The bloat and corruption you speak of is not some trifling side issue.They are defining characteristics.There is much prattle of love of country, but where these clowns feel their position is threatened, they will mow down Thai citizens in the street. Thailand has no foreign enemies.
Anyway keep on drinking the Kool Aid.
