I think the wealth shifting idea is supposed to lend economic stability to a wide geographic region. That will tend to reduce migration between those regions, and tend also to lower political tensions. The EU should also open a wider market for trade and that should give economic growth to the members of the EU. I realise there are very different perceptions as to how well this is working.
I don't see why our economy failing would bring down the US economy. They may fail for the same reasons but it would be coincidence rather than causality. I think the US economy failing would bring down the global economy. If the US agree that our economy failing would bring them down, it is perhaps telling their president wants us to remain in the EU.
I think Asia is growing because it has cheap labour which is becoming better educated. But also because the big players have two huge internal markets for their products. China and India. I also think those markets have benefited from the ease of movement of labour towards the areas where growth is centred. Bangalore, and Shanghai, for example. They will start to lose ground when their economies strengthen and the workers demand better pay relative to others around the globe. This has been happening with IT, which I think is relatively easy to move because it's a service rather than a physical product. There was a lot of growth in India, and still is. But India has become relatively expensive so European and North American companies have looked elsewhere. Malaysia, for example. Globalisation is doing what the EU is trying to do, but it's working fastest in the physically large nations which by definition have no or low barriers for trade and migration; Brazil also.
My worry if we leave the EU is that much of what is left of our manufacturing might go because much of our manufacturing is foreign owned and here because it's easy to push those products into the EU. My big local employer is Ford. If exporting to the EU becomes more expensive through additional administration and maybe tariffs I'm sure they will review their location. If they moved, thats a big impact to my local area. They are not going to suddenly send a load of Transit van engines to the US to make up for it.
Problem is, I don't know. I certainly don't think we'll fall apart if we leave the EU. I do think we'll notice the change. So I will take a punt on my best guess as to what that change might be on whatever day we get to vote. Living in a very safe parlimentary constituency I am at least enthused that for the first time ever I have a vote that means something.
I think I lead for the poorest adherence to the vote, dont comment ethic of this thread.
