Una and Andrea's United Ireland

When we saw Samuel Brazys, an Associate Professor at UCD tweeting that 1,257 companies with a combined turnover of 68 billion (= to 17.5% of Irish GDP) work from one office block on North Wall Quay in Dublin, we had to know more. We wanted to know about GDP, GNP, GNI*, tax loopholes, whether we have any intangible assets we can move to a tax haven, are we a tax haven on purpose, what's a double Irish and should we do away with all these maybe fake measurements of our economy and change to Gross National Happiness like Bhutan and New Zealand?
