You are a doctor but you are so poor with number. Before you claimed that there are ,more Vietnamese professional people in the jobs, you ought to learn about the population of your Vietnamese in Vietnam and about the population of others.Laos has barely 4 million people, not including the intruders (Vietnamese); Cambodia has about ~ 5 millions after their famous killing field may be included with the intruders (Vietnamese hidden soldiers inside Pol Pot army dressed as Khmer civilians), Thailand has about 65 million people, but Thailand is a peaceful country, the Thais are not refugees as the Vietnamese, Khmers and Laotians. The same applies to Malaysia and Indonesia. Their countries are not suffering from a warmonger like in Vietnam, thus you cannot compare yourself a refugee to others who are not here many like yours. Their countries are peaceful countries they have no reason to pouring by boats to the US or other western countries like the Vietnamese. The population of Cambodia today rises up to around 14 million people including the intruders (Vietnamese) about ~5 to 6 millions in Cambodia. I estimated this I didn't include the warmongers (hundred thousand of Viet soldiers) hiding all over Cambodia, in island: Koh Kong, and at the Thai-Khmer border.
