I think the party's over for the Celtic Tiger of yore, Ireland was able to attract a lot of foreign investment in the the past. Many U.S. companies—including Dell, Intel, and Gateway—were persuaded by the Irish to move some of their operations to Ireland because of its EU membership, low tax rates, government grants, and well educated, English-speaking workforce, but with the EU wanting to level things up of late, the Irish are beginning to squeal, whether they have the stomach for full independence & Irexit I don't know.
The smart move would be to align themselves with the UK but of course, history wont allow that.
