For example, consider the role of economics in the case of Germany's reunification. Despite initial popular approval based on politics, the reunification of East and West Germany has been proven to have been rushed without economic considerations. The gap between East and West's economies forced the West to spend much of its resources on getting the East somewhat to par. Even after twenty years parody has not been achieved.
The difference between the two Germany's right before reunification was stark. The East German GDP was only 10% of Germany's total in 1989 despite having 20% of the total population. Per Capita wise, East German GDP was 42% compared to West Germany's.
Now examine Northern Ireland's economy in relation to that of the Republic of Ireland and the United Kingdom's.
- Northern Ireland's GDP is 30% of all of Ireland though it has 39% of all the island's population. Per Capita wise Northern Ireland's GDP is 60% compared to the Republic of Ireland's.
- In comparison to the United Kingdom: Northern Ireland's GDP is 1.5% of all the UK's GDP while being 2.9% of the total population. Per Capita wise Northern Ireland's GDP is 79% compared to the UK's.
- GDP per capita is closer to the United Kingdom's rather than Ireland's. Cost of living fluctuations would cause more harm than good for the Northern Irish citizenry.
- The sheer size of the United Kingdom's economy allows it to better support (i.e. prop up) Northern Ireland. Ireland would be forced to spend a much larger share of its resources on Northern Ireland much like West Germany had to do for East Germany. This is unreasonable with the republic currently suffering a massive downturn.
