We either have a weak pound and attractive pricing for those abroad buying british manufactured exports, or a strong pound and attractive prices for those here buying foreign made imports.
Either scenario affects labour volume and pay rates in opposite ways, and whilst our workers get taxed at a constant never fluctuating level, any short term balance achieved for long term growth will never last long enough to kick-start incentives by those companies that could make a difference.
Change of balance at the level required would take generations, beyond our lifetimes. By then, technologies and manufacturing expertise will be so spread out and comparative world wide, that the geographical area of manufacture will not matter any more.
'Made on Earth' will be the norm....after that, taxation, healthcare and social safety will determine what makes a country great.
