As a side thought: it is oft remarked in the defence industry circles how buying local might be more expensive but more of the money stays at home.
Quite apart from any sovereignty arguments, cash spent at home goes to purchase of hopefully local components, materials, all along paying for local salaries, which drives local economies. And this is taxed along the way too, as income tax, VAT and ultimate corporate tax.
I wonder if that's really true to a significant amount, and if so, how much does that matter. Eg if I can buy something for X abroad, or c*X locally, for what value of c is this overall breakeven?
