But to 'support British manufacturing' enough to enable them to make goods that can compete would mean fewer regulations, lower wages and longer working hours.
The truth is, manufacturing is a dirty business. When we had a lot of it, our rivers were heavily polluted, some of our beaches were black, etc. We are STILL cleaning up after over a century of industry.
Yes, there was more work for a population more willing to get its hands dirty, and I speak as, I suspect, one of the few posters who worked for not even minimum wage because it wasn't a thing 30 years ago, on the factory floor.
But today is not yesterday. We don't want the smell, we don't want the dirt, we want proper wages and flexible working hours, but at the same time we want manufacturing back? Not going to happen. Companies don't want to pay to meet more stringent criteria when they don't have to elsewhere.
As I said before, we all want the stuff, but we don't want those production values (or lack thereof) on our doorstep. It's been convenient for decades to ship the unsightly truth of mass production for cheap products somewhere where we can't see it and don't have to manage the waste it produces.
If we had to live and work with manufacturing that could compete with the prices of that which we import, we really wouldn't like it. When we had poorly regulated industry, we fought to clean it up, make it pay better, etc. But the reality of clean, modern, well regulated production is that it costs. And the businesses don't want lose profit by paying it, and the consumers don't want to pay the premium of that cost being passed on.
Decades ago, the decision was made to simply shovel the mess elsewhere, including landfill from our consumption. If we were still producing and having nowhere but our own shores to dispose of our own rubbish, we might be thinking about this a bit more, beyond 'I'm skint, but it's my right.'
The trouble is, we've not just outsourced production, we've outsourced the impact of low cost mass production, and have forgotten/don't want to think about what it actually looks like, and how that pertains to a nation that doesn't want to work for peanuts in an unsafe environment for hours on end and rather likes our rivers having less chemical waste in them, but at the same time wants everything to be cheap as chips.
