Currently, Northern Ireland’s economy relies heavily on the public sector, which employs more than 25% of Irish workers.
“Streamlining” public services in the event of a United Ireland would mean laying off a huge amount of these workers, or, at best, forcing them to relocate to Dublin to replace workers who have been laid off there.
In addition, the quality of many public services could deteriorate if they are provided on an all-Ireland basis. The police, for example, has been a difficult topic in Northern Ireland and it took a great deal of work to create a functioning police force with cross-community support in the PSNI. Replacing this with the Gardai would not be an option.
Furthermore, the transition process would be extremely expensive and would swallow, and perhaps surpass, any of the savings afforded by more efficient cross-border services. Not only would road signs, legal documents and many other things need to be changed, but police costs could skyrocket due to the heightened potential for violence and increased instability.
Many of Northern Ireland’s largest private companies, such as Bombardier, also do most of their business with the UK, meaning that a United Ireland would introduce an unnecessary obstacle rather than streamlining the economy.
