Tariffs - NOT amateur radio

The USA has already imposed heavy tariffs on Canada, Mexico and China. It is threatening tariffs on the EU and UK. Whilst I can (I think) understand the reasons, my view is this is a blunt tool that can do much damage to the world economy.

Like it or not the world is very interconnected with supply chains that go the world over. Whilst I can see the incentives to keep things local, this will come at a cost. Suppliers nearer to home are likely to have higher labour costs, so things are likely to be more expensive.

The USA may be big enough to cope on its own. Much of the world cannot. 

We may be at the start of a new world order with the USA (for now) forging an isolationist policy, unlike the rest of the world. It will be interesting to see what happens.
