Equally, the will of shoppers is to buy things from Primark et al. Personally I think it would be utterly absurd to 'rebalance' the economy towards agriculture, and thankfully the industrial strategy makes no such suggestions. We benefit enormously from global trade in agriculture and manufacturing, and equally we benefit enormously from global trade in things we do exceptionally well, like services, life sciences and engineering.
You mentioned clothing earlier, and we have a thriving fashion industry, but as befitting a leading economy, that fashion industry is in the high value-added stuff like design, not low value-add like manufacturing. Indeed, it's estimated that the fashion industry generates roughly 3 times what agriculture does, but financial and business services are 5 times that. I'm afraid if we try and force companies to re-shore low skilled work, then the work may come back, but it will be done by machines rather than people.
