The Thai guys my age who live/work here in Bangkok near my house ALL hail from Isaan, yet all speak Central Thai just fine. Then again they've lived/worked in Bangkok for 10-15 years now, so I'd imagine even they've adopted the "when in Bangkok speak Central Thai" adage (if only to stop the overt racism Bangkokians have for Isaan-ites). Don't get me wrong, most of them speak Isaan and the guy from Surin speaks Cambodian too.
I was only relating my own personal experience that Thais, the country over, seemed more than willing to converse in Central Thai with me during my travels around this country. Then again, the choice was speak Central Thai or English, so in a way that backed 'em into a corner.
I agree with "Borey the Bald" totally as far as generation by generation you can see the increased use of Central Thai due to access to the Thai government education system.
Thankfully, (for the younger Thais) we're also seeing an equally exponential growth in Thais using English; which is far more important on the world stage for the Thais at this stage of the game.
Gone are the days when Thailand was insulated and could afford to adopt the pretentious (yet totally predictably Thai) mindset of; "I'm Thai so I don't need to speak English".
Given the way the Thai youth of today, even in one buffalo villages in Nakhon Nowhere, are connected to the internet; I think this next generation is gonna really come into itself in regards to finding a 'balance' between their innate "Thai-ness" and the need for English as far as their future is concerned.
