A bigger problem is getting referees of any classification. Like many others, I'm well able to question a referee's decisions but I admire anyone who does the job. Yet, I would be slow to encourage family or friends to undertake the task. Only last weekend, another physical confrontation with a referee in Gaelic games made the headlines (here).
Maybe we should treat referees like the other service providers in Gaelic game, e.g. pay them the same rates as the service providers such as Strength & Conditioning coaches. Lip service about respect only goes so far. Even as an economist I realise that there are limits to what money can buy. The philosopher Michael Sandel, in his book What Money Can't Buy and associated YouTube clips, has some nice examples where payment can show a lack of respect. Imagine a friend invites you to their parents' house for dinner at Christmas. Then, after a wonderful time, you pull out your wallet and ask "how much do I owe you?" I don't think any referee would be offended by getting the same amount of money as the service providers to the competing teams.
