Increasing automation is going to make unskilled labor a huge liability for countries. This is one reason I don't think some of the anti-immigrant position of many Americans (and Europeans) is unwarranted. Every country should want highly skilled labor to help improve their current account, but unskilled labor is huge future liability. There is already a huge surplus of domestic unskilled labor in developed countries. Allowing unskilled labor to increase through immigration is only going to exacerbate the problem.
