The same applies to the international business.
If one nation improves its productivity and increases its export, its unemployment rate will not rise immediately.
However it might be an export of unemployment to another nation.
The rise of unemployment rate in another nation may cause social unrest there and the exporter nation may need to increase its tax rates to help the other nation.
If it did not help the other by increasing its tax rates, it would face the consequences sooner or later, such as, terrorism, wars and/or refugees.
Just to make sure, I would like to say that the problem does not exist in improvement of productivity or free trade.
It exists in blind belief like as “completion is good”, that is, an illusion.
I think that there might be phobia for defeat or a shortage in the subconscious minds.
