Don't you think if that was possible they would have? English speakers are getting more and more difficult to find off-shore. Dell found that out and moved their business to business service back to the US. Of course, consumers are screwed.
Most businesses want to be as close to their customers as possible to reduce shipping costs. If it's more of a financial advantage to move overseas, they will. If shipping costs outweigh the benefits of cheaper taxes and labor, they stay.
The proximity of a business is only necessary if the business has interaction with the customer. Barber, yes, customer support, no.
The ONLY advantage of off-shoring is employee pay.
Shipping costs are minimal, ask Amazon.
I'm not talking about shipping a single jump drive to a customers house, I'm talking about bulk shipping back to the US.
When imported goods come in, they don't drive a ship to your local Walmart store. Those ships have to be unloaded at various ports around the country. Once unloaded, the freight has to be inspected and counted by dock workers. Paperwork must be processed and recreated for shipment out of the shipping docks.
From there, those goods get loaded on trucks (or trains if they have tracks in their port) and hauled off to warehouses across the country. If by truck, the truck can go directly to the warehouse. If by train, a truck has to go the train station to pick up those container trailers and then haul them to the warehouses.
Once at the warehouses, the freight has to be inspected again, at times, by border agents, repackaged at times, and more paperwork needs to get processed. Once that is complete, local trucks pickup the freight and deliver it to store warehouses and the process repeats itself.
Finally, from the store warehouses, trucks have to deliver those goods to the stores themselves.
It's a very costly operation. And from my experience, there is also some freight damage that somebody has to pay for. Many times I have picked up damaged overseas freight and had to mark it on the bill of lading to protect our company from being accused of doing the damage. I still deliver the damaged goods, but our customers have to ship those goods back or throw the items away.
In a few cases (particularly with China) the cost of getting low quality or damaged goods, having to ship it back to China, was more costly than just having the parts manufactured or processed here in the US. Some of our customers just quit doing business with China.
