If America had followed up on its tremendous victory in 1968, unification would have followed shortly and the Communists would all have fled to Russia and China. As it is the Vietnamese are naturally dealers and businessmen. The Catholics lead the new business attitude when the Government decided that collectivism doesn't work and tried something else as the Vietnamese, even the Việt Communists do, unlike the Russians and the East Europeans. The Catholics quickly became the Business Class because Christians and Jews are the only people on earth who can do trade and business outside of clans and families. If a Jew and a Christian make a deal each has a reasonable expectation that the other will keep his end of the bargain. They
trust each other. That is almost purely a J-C characteristic. In every other culture that is not true. Everything is taken advantage of for the clan One does not tell true information to any outsider. Deals are cheated on or perverted for the immediate benefit of the clan.
The Buddhists, especially the Mahayana variety are practical people and when they see the Christians succeeding with Trust and Integrity they imitate and do it too. Việt Nam is visibly more prosperous every time I go back at short or long intervals. It is becoming t a Judaeo-Christian culture in some respects even while not having more than maybe 10 or 11 % Christians and almost no Jews.
