Immigration and the debate we never have

One thing never heard in any debate on what we should do about mass immigration is the argument that we cannot have mass immigration because how will Tesco,Asda,Lidl,Pound shop cope with the demands of all those people coming into the country.No,we only hear the argument how can the NHS,our schools our transport,social services and all the state infrastructure cope with all the demands made upon it by the immigrants. The solution then is staring us in the face.Let all those services be run on capitalist principles,then there would be no shortages,no waiting lists.But of course we are wedded to a discredited 19th century ideology of socialism,so we end up vexing about how many people can come into the country ,in other words approaching the argument entirely from the wrong end .Open borders under capitalism are no problem but it is impossible when people are dependent upon inefficient corrupt state public services characterised by incompetence,protectionism,lack of innovation,  and stagnation.Capitalism is the answer to immigration,socialism is the problem.
