I like the principle behind this idea, but to balance practicality with principle, I have to modify it slightly to be more feasible as an easily achievable permanent practice:
1. Rather than ruling out "all imports" I'll modify that to those from countries using the modern version of slave labor instead of paying their workers a living comparable to even what those on minimum wage in industrialized nations get. Therefore, I'll be excluding more than China. I will, however, continue to buy things imported from the USA, the EU, and Japan.
2. Practicality may need to over ride principle as sometimes options on certain products are going to be limited to where I can't buy locally or from a country that isn't using underpaid slave labor. In those rare cases, practicality will win out.
3. Related to (2) there is a point difference where preference is going to, again, have to give way to practicality. I can't express it as percentage because if its a one buck item, or a few bucks, the percentage difference would have to be significant (like 200%). While on big ticket items, paying even 50% extra may again mean that practicality trumps principle.
To the absolutists who may fault this approach for its caveats, my only reply is that in being a more everyday approach, its a long-term sustainable one. And over the course of year, or a lifetime, this balanced principled approach will lead to drastic reductions in overseas spending on 3rd world imports compared to blind buying where tags aren't looked at, or indifferent buying. Its not perfect, but I'm not an income level where I can just eat say $2,500 to on a 10k purchase to stand on principle. However, over the long term, the amount of money not spent on goods from these countries will be considerably more than $2,500 - just spread across more purchases that make it more feasible and sustainable.
I would recommend a similar approach for anyone else who is tired of seeing more and more of countries wealth and employment being exported wholesale to 3rd world slave labor style factories. Taking the multiplier effect into account, the more of us who go this route, the sooner the scale will start to tilt back. Nobody else is going to do it for us. The only ones who can change the status quo is each of us, one person at a time. The cumulative affect will be dramatic.
