The Issan situation is so revealing of the flawed Thai thinking.
Vaccinating Bangkok and shifting the infections to the Provinces is a sad stupidity.
Containing the epidemic at the country level would have required a stringent lockdown of the deep read provinces, country wide vaccination by risk group, allowing travel only for fully vaccinated people and medical emergencies.
Maybe it wasn't flawed thinking, just utter contempt of the Bangkokians for the Provinces and their cheap labor.
