Economic theory really is pro-immigration

"Widespread biases on economics are far from being harmless. Wrong ideas held by voters usually lead to catastrophic policies due to the inherent nature of the democratic process. In other words, in most cases, politicians undertake those policies that they deem popular among voters in order to get reelected. If those policies beget pernicious consequences for the economy, harmless beliefs turn into lower living standards for all. Of those four biases, the most potentially harmful is the anti-foreign bias. This inclination to underestimate the benefits of economic cooperation with foreigners manifests itself politically in two main ways: protectionism and anti-immigration policies." (05/15/17)
