How, exactly, do we do that?
In my industry - textiles - unions pushed the jobs overseas, along with government "safety" regulations.
While you might be able to set up a t-shirt manufacturer in the US (there are a few) the prices they have to charge keep them from being truly competitive. For instance, I can buy a made overseas (Honduras) white adult t-shirt for $1.30, blank. My print costs for a two sided print (like you might get at a 5K run) are about $2. I will sell that shirt for $6.
A shirt with EXACTLY the same specs, made in the USA, costs me $3. Print costs are the same - about $2 - so to make the same margin I would have to sell that shirt for $9.09.
So to bring manufacturing back to this country (in textiles anyway) we either have to be willing to pay much more, destroy the unions, and/or roll back "safety" regulations. Good luck with that.
I hear you, FRiend. Unfortunately, we have allowed into our House someone who has promised to Fundamentally Transform™ this great nation. I don't see unions or regs going away any time soon :(
