As I took my place in the cavernous main hall of the Curragh racecourse, the headquarters of Irish horse racing, for the IFA pre election day event, I thought inevitably of the Irish thoroughbred horse breeding industry, an Irish industry as big as those of Britain and France combined.It may well be our most competitive sector across the entire Irish economy, but it’s one based on a rigorous meritocracy, with breeders of group one winners standing to make fortunes on the world stage and others falling by the wayside.
