While in principle I am in favour of free movement I agree that we have to have some controls and limits. Mass migrations disrupt and play havoc with communities. People from outside bring great benefits and enrichment as long as they can be properly integrated and the infrastructure is there to deal with them. When there are too many it creates strains and people are not assimilated into the culture. There is also the fear of terrorism to contend with. Some processes need to be in place to deal with migrations.
