I think 'optimism' is the only reason for thinking it might be a better comparison! But you are probably right, somewhere between the two would be a good comparison. Denmark has a low corporate tax rate like ourselves (albeit a higher rate). Though it differs from Ireland in being home to many multinational companies (Carlsberg! Maersk, Lego, Bang & Olufsen etc.) and in not having such an inflated property bubble as ourselves.It might be a better comparisson.
