The phrase "We've never had it so good!" has been widely attributed to British PM, Harold McMillan supposedly speaking in 1957. What he actually said was "Most of our people have never had it so good" but quotes do tend to get mangled over the years and recycled in their punchiest and most reductive form.
The Irish Times's Cantillon, like certain Brazilian players goes one name only (cf. Neymar, Paulinho) so it's clearly a mark of genius in one's field. Anyway, he/she recycles the above quote as a question with respect to the Irish economy: Have we ever had it so good?
The answer would appear to be a resounding 'no' and the arguments, dear reader, are compelling.
