Personally I think labels like "nationalist" are unhelpful, but regardless what you label it what I do believe is that there needs to be a genuine conversation about whether it's better to have more expensive goods and services if it means people have jobs and opportunities.

I'd be fine with iPhones costing 2-3x more if I knew they were built domestically. Those who couldn't afford them could always buy second hand or hold on to them for longer. And historically of course this was often how things worked... People brought quality clothes or quality furniture and looked after them for years – decades even. Whereas today because we can exploit foreigners for super cheap goods we don't really care if we need to buy a new pair of shoes every 6 months – it's created a completely different economic model and one that a skilled worker cannot compete with, at least on price.

Perhaps the economy on the whole wouldn't grow as fast if there were more protectionist policies, but at the same time I'd be amazed if it didn't significantly improve job prospects and inequality.

That said, we almost everyone in the middle-class deserves to lose their jobs to foreign workers for how awful they've treated those below them for struggling to find good work in the era of globalisation.
