If tax wasn't your sole motivation Tim (which it obviously was) then you could have located in London, which is a vastly bigger city with a huge talent base.
1980's London? You having a laugh chum?
Maggie had other things on her mind back then, like driving the economy off a cliff.
Ireland has a corporation tax rate of virtually zero. Every other European nation has rates around 20%. Ireland is a tax haven, which makes them rather unpopular around these parts. Except perhaps with Jean Claude Junker, the EU president, who used to run the EU's other tax haven - Luxembourg. The EU is such a mess.
Not long to go now. Britain will not have to worry about the internal workings of the E.U.
The Irish Government could easily just say to other E.U countries to drop their tax rate if they want to compete. 20% sounds a bit high to me.
