This may come as no surprise, but I think DOBs article isnt very useful. Its hard to believe that he has written a full article on wage disparity, with repeated references to the UK as a guide, without considering any of the political turmoil that Brexit is fostering and the underlying reasons of why that vote went through, in no small part because of wage stagnation.
I get the impression that he believes
average public and private sector wages should be on par with each other? What he doesn't say is if UK wages should rise in line with Irish wages or should Irish wages reduce to UK levels. I suspect the latter, but given everything that is occurring in UK with Brexit, due in no small part to subdued wages, it is unfathomable that he could propose such a notion.
He appears to consider that in 2018 that if wage levels reach 2008 levels that this is a bad thing. It would be interesting to know when he thinks it would be safe to reach 2008 levels? 2028? Certainly property prices, rents, energy, transport, groceries etc are all close to, if not in excess of, 2008 levels, so why not wages?
Also to compare average public sector wages and average private sector wages is comparing apples and oranges.
The private sector has an infinitely broader scope of trades and businesses that simply would not have any function in the public sector. A lot of those trades are often synonymous with low pay - fast food, hotel & restaurant, retail, hairdressing etc.
If you excluded all the low pay work in the private sector that has no functioning in the public sector then average private sector wages would rise pretty quickly.
So if you compare wages in both sectors with comparable jobs, then it tells a different story.
For instance, do private medical consultants earn more than their colleagues in public sector?
What about the General Secretary of a government Department and say a, CEO of a private bank?
Im sure there are variances in both sectors with either doing better or worse than the other, but I suspect if it were analyzed in detail the 40% disparity would shrink considerably.
I think this is a good starting point;
The highest average weekly earnings of €1,133.51 were in the Information and Communication sector, followed by the Financial, insurance and real estate activities sector at €1,119.36. The lowest average weekly earnings were €356.29 in the Accommodation and food service activities sector and €482.91 in the Arts, entertainment, recreation and other service activities sector. See table 1 and figure 2.
