I already do what I can to buy local. I try hard not to go to places like walmart and big box shops. I do ask where things are made. I think export/import relations are important, but I think we have been inundated and need to slow down.
I was thinking about this a while back. Maybe what is causing so many of the problems is the live frugally gurus. Trying to get everything as cheap as you can just leads to a drop in wages and everything else that goes along with it, so that eventually everyone has to be cheap in order to afford anything.
sometimes thats the trade off for good work conditions versus cheaper goods.
I do think you need to promote your own industries. In economics, they talk about economies of scale etc, but those are generally in a controlled environment. You need to be able to create the equilibrium that fits both maintaining local production and jobs and being a player in the global market.
There is also an asset in having skilled staff that you loose by buying from overseas,....
