Actually
Not much of a beer drinker.
I must say, if you check service delivery and management ethos among the foreign educated younger Vietnamese (check out the tech start up scene) and among the overseas Vietnamese who have returned, it is on par with Oz, UK, USA etc
That said they have huge problems opening up the mindset of local rural Vietnamese and their elders, but they are fast learners. Talk to the pilots trained overseas who fly the 321, they are night and day different in their outlook to their fathers flying the 777.
On Vietnamese TV is a show about 5 woman who are all over 30, single, childless and professionals, so the times are a changing. I laugh at your assessment of 300 years, in that time the U.S. went from colonial upstart to World power to now still strong but fading superpower.
