"The government's role in this is their idiotic role over decades of signing free trade deals without "balance of trade" clauses. So when DoH outsource payroll jobs to Steria, or DWP outsource IT to HPE, who then move them to South Africa, India or wherever, the UK jobs disappear, the demand for the administrative, systems and mangement skills reduces, and the exchequer lose employee and and employer payroll taxes."
and when companies do it, they all ultimately are simply losing customers. A $40k job in the UK replaced by a $10k job in India, means the $10k person in India is not buying German or Italian or UK cars. They're not buying any products and services the UK (or EU) one would buy, they can't afford them.
