Apparently the lousy VC and NVA could have spared their nation millions of deaths and decades of misery by merely giving the US plan a chance in Vietnam. South Korea, Taiwan, Germany, Italy, and Japan have already proven beyond doubt that US military operations since 1940 can lead to freedom, independence, security, and prosperity, if local people so choose. The anti-commie crusaders of the cold war were apparently correct in their assessments of communism, socialism, capitalism, and democracy. As we see here in Vietnam, "planned economies", with rationed and "universal" healthcare, housing, employment, land, etc. produces a universal average far less than what free markets do; in the case of Vietnam, extreme socialism produced extreme poverty, scarcity, hopelessness, and misery. As in China and India, reduction of poverty in Vietnam has proceeded only as a consequence of increased market freedoms.
Socialism promises perfection, but delivers far less than the accurate capitalist promise of imperfection.
