Re: Race to the bottom
Consistent growth of fibre connections to the US and UK, with France to follow, and the Hibernian spar will mean roughly equivalent speeds to what London gets - although if you move away from Dublin or Cork to the west, your mileage may vary. Highly rated universities turning out a well educated english speaking work force every year. Ireland if not without Finance Centres and services either. So the only legitimate issues you mention are a better tax rate (and the UK has not got a great track record on this either), and a middling climate.
You come off somewhere between bitter and vaguely racist, although I'm sure this wasn't your intent.
