Great article Philip. And who (on our liberal side) could be against ‘openness’?
The problem with the open/closed frame is that it ignores some ideological and material political aspects. For example, open globalised trade has created productivity, generated growth and increased choice. But it has also been accompanied by relative inequalities and the erosion of a sense of community and identity for many — if not most. Unless the open is also inclusive then it will rightly continue to accrue more distrust.
