One advantage is that it would not be a one industry town. Industries also seem for many reasons to fade out or move out or whatever at some point of their cycles. Losing all you have from an industrial perspective is a heavy blow for a community.

Some industries are more aware of their own presence in a community and some just view it as a place to operate.

Detroit was a one industry town basically. In their case it pretty much destroyed the community. There were other reasons as well for the depth of their fall I suspect.

From my perspective most of the remaining industries are at or will be at risk from production of simular items from the orient. Many companies have already died off in the thouands or tranfered their operations there.

The few I thought might be somewhat secure are now coming under attack. Some companies that left I would have considered to have been national treasures. The long term loses by these types of companies leaving are totally unacceptable.

Also this enabling development of things in china especially that may not have happened otherwise or taken a much greater time frame to achieve. Even the japanese have set up the facility to build the honda fit in china denying their population the jobs as well as giving up whatever manufacturing techology was invoved. History will find out that the so called smart corporations will lose control of their operations there and they will become over time pure chinese entities.
