Inspired by Brexit that can boost Dublin’s finance hub, says Central Bank of Ireland's report and Duff & Phelps's Global Regulatory Outlook (GRO) report.
Ireland and UK are similar because English is an official language (Irish is the other), and Ireland uses common law. But Ireland has a codified constitution unlike U.K.
Like What single change would have given the best chance for Iraq to win the Iraq War?, I copy and paste the customary disclaimers.
The financial hub can be anywhere in Ireland, not just Dublin. But it can't be in Northern Ireland that belongs to U.K.
The new financial hub just has to be way more powerful, financial than London. London doesn't have to lose its world city status.
The smallest single change must be justified realistically and must involve the least amount of changing the world as we know it in 2020. So Ireland can't just suddenly abolish all taxes, or suddenly discover secret nuclear weapons faster than everybody else.
The change has to be a single event, or a collection of compact, tightly coiled events occurring in a short time period. History should appear similar to what happened in real life.
