Everyone makes some valid points. You can manufacture in the US but it is much more difficult. The US just is not set up to manufacture anymore for a lot of items. Sure some stuff you can do but a lot is much easier to do elsewhere.
Then there is the cost factor and availability. You can't sell what you don't have. I would love to see a large scale consumer study of two identical products, one made overseas, in stock and 20 percent less in price. I bet I know which one most consumers will choose.
