The Immigrant Factor and Effective Altruism

The immigrant factor that the types of people who immigrate to a country are going to be on average more well protected. There's a huge amount of health selection on immigration too. So they may be coming from countries where there's high infant mortality but if you immigrate to the United States from Nigeria for instance you obviously didn't die as an infant so you got through that part of it. And those people tend to be very ambitious, very well put together, do very well.
