They can probably try to do that but Margaret Thatcher completely destroyed the UKs manufacturing base in order to screw over labor unions. The Thatcher theory was screw over manufacturing in favor of financial services. She was widely praised by the financial press for doing so. The plunging pound does not help the financial services sector, it hurts it. Then there is Brexit which seriously hurts both the manufacturing and financial services sectors. So the UK can increase manufacturing but it will be a long hard slog after they intentionally and continuously gutted the sector for the last 30 years.
