If I were you I really would stop demonstrating how little you understand about the situation here, socal.
If the banking system is swamped with the proceeds of crime (drugs, theft, counterfeit goods) to such an extent that institutions outside Thailand no longer trust the banks or the currency then corruption has a very considerable effect on the value of the currency and especially the country's ability to export.
You can keep reading about the country's GDP all you want though, but it is historical data. Thailand is like a duck on a pond; calm on the surface but paddling like heck underneath. When the paddling stops you don't want to be the one with a bank account full off Thai baht and a book full of historical data from the good old days.
