Picture a planet where the human race exchanges raw materials, products and services without restriction.  This senario puts all product and service suppliers on equal footing.

In this idealized situation wherever you were on the earth the price or cost of goods would be limited by natural attributes.  At the simplest level access is based on availability and demand.

Competition would be founded on the producers abilities without constraints of artificial controls like tarrifs, duties and other types of border controls.

And the Con’s

National identity requires differentiation.  A way for the population to say “My country is better than yours.   Managing your national identity requires  control over outsiders.

Our nations exist so we can collaberate jointly to support the overall populace through leadership (governance) and laws.  Setting boundaries is a key aspect of this.

Each countries internal economy and national culture tend to be unique in some ways.  Open borders make it more difficult to maintain this singularity.

At what Cost?

Freely exchanging goods and services around the world will probably increase access and lower costs.  This would ultimately improve world wide economic activity.

The insular approach lowers creativity and can result in stagnation.  Japan of the seventeeth and eighteenth century is a very real example of this.

The country was virtually closed to foriegn influences and as a result  national development and creativity stalled.

Ultimately the human race would probably benefit greatly by thinking outside of the box.  Blow away artificial limitations and be free.
