1. Maybe Vietnam got shafted *because* theyre gullible. There is probably a delay in skepticism settinh in.
2. Americans are probably more skeptical now than ten years ago despite egregious bail outs happening at that time. Skepticism takes time. Most do not know how money or banking works but they do know whether theyre better off vs ten years ago.
3. Much of this seems cultural and uncorrelated. America x Austrailia are close whereas Vietnam x China are also close.
