Does it really matter to you or me or the Thai on the street? Leaders in politics don't make a difference, it's the leaders in the civil service who do that, quiet unsung heroes who make sure the political idiots don't sink the boat.
Political leaders in democracies don't last long anyway, the civil service is the marathon runner. Even in ancient Rome it was the advisors, often educated intelligent slaves, who advised the executive branch, in Egypt it was the priesthood, in ancient Sumeria they actually had a functioning civil service as did the ancient Chinese dynasties.
Catastrophes can only happen when rulers ignore the civil service, ride roughshod over bureaucracy and make their own decisions, they usually come to a bad end.
