don´t worry. Viet inferiority complex will in a future time become Viet superiority complex. They will trashtalk Koreans all day long, just wait 15 years. Vietnam comrades are also eager to learn English and I think will be even more English proficient than Filipinos in a few decades. At least this comtemporary begging is a good sign that they wander out of the communist firewall and explore the outside world. The more they explore they more they learn just how shwitty their country actually is.
