For the nation as a whole there's a lot of wealth being created --average real wealth is just about at an all-time high tho it may be peaking when we should be continuing a climb. Wealth is always concentrated but these days it's more so than ever. Measuring just how much is foggy because of all the politics and controversy.
A nations wealth is created in only three ways: by mining it, making it or growing it. Importing and retailing are not wealth creating enterprises.
