Chang and Eng were the first internationally known “Siamese twins”, as a result of their having been exhibited worldwide. Although each had a complete body, they were joined together at the sternum.
In 1870, Chang suffered a stroke and his health deteriorated over the next four years. In 1874, at age sixty-two, he developed bronchitis and died. His brother Eng realised immediately that his continued attachment to his brother meant that he was next. Although he was separated from his twin in an emergency operation, Eng died hours later. He left the problem too long and paid with his life.
Just as with Siamese twins, it’s a risky proposition for one country to have too much dependency on another. If a visitor to Uruguay were to visit a supermarket and examine the origin of the products by reading labels, he would find that Uruguay produces 90% of the food it consumes. In Cuba, however, we read the labels on packaging and see that the great majority of packaged foods comes from Mexico. This suggests that, should food production diminish in Mexico, or should there be political turmoil or shipping problems, Cuba could face significant problems in feeding its people.
A similar problem exists in Canada. Roughly 70% of Canada’s export product is sold to the US, whilst over 60% of its imports come from the US. Of particular concern is oil. The Canadian oil industry cannot survive without the US, as over 99% of its oil production is shipped there. Unless oil returns to a level over $60/bbl fairly soon (don’t hold your breath), and the US doesn’t stop dithering over the pipeline issue, not only will Canadian jobs and oil sales suffer, but entire companies are likely to fail.
Regarding banking, Canadians take pride in their system and rightfully so, as Canadian banks have been nowhere near as cavalier as American banks in recent history. However, without transfers between the two countries (particularly between New York and Toronto), their banks would quickly find themselves in peril. If the US were to find itself in an economic crisis, as appears likely, Canada’s banks would also be in crisis.
