We have net migration of 750,000. Do people even think about how much that is? If we need that many immigrants we are a failed country. Our education system needs to be vastly improved.
But that's not the point of this amount of immigration largely. We are only aiming to build 300,000 houses a year and yet we have a housing crisis and are taking in net, as many people as a large city each year. The reason is to keep wages low and house prices high.
