The only publicly acceptable approach to immigration seems to be, more or less, stating “immigration is a problem” and then making vague promises to control it in some way. This was particularly obnoxious in the run up to, and aftermath of, the referendum but it has been the case for some time. If we really want to stand out, and promote a truly liberal approach, we need to do the opposite. We need to stand up and say “immigration is a solution”. As liberals we understand the importance of everyone being able to pursue their own good in their own way. This entails a positive approach to immigration. Right now we should be pushing to make sure we retain free movement within the EEA. In the future we should be working to liberalise migration arrangements with the rest of the world as well.
This doesn’t mean that in practice we have to advocate for completely open borders, no matter how ideologically attractive such a system might be. There are genuine issues with rapid population growth, such as short term strain on public services and downward pressure on wages, and we should address these, but not by following the popular route of promoting the illiberal idea that immigration is a problem in itself. Instead we must emphasise the benefits of immigration, both in economic terms and in terms of individual freedom, and confront the myths that support the xenophobia behind a portion of the Brexit vote.
