Mostly wealth, its a long time since the industries of Dublin were beer and biscuits.
It still makes beer.
True, the economic model is based on the lawyers and accountants trimming regulations, not actually producing anything. Our country cousins have agriculture and agriindustry. They do produce things. Their infrastructure is based on getting product to Dublin quickest. Wealth is centred in Dublin, it is not enough to say Dublin makes its own cake and the rest of the state by incompetency doesn't. The process is a lot more interconnected on actual product making streams.
