Our economy being too centered around Dublin.

It annoys me too.

But, do we not have 50% of our population in Dublin to match the 40% of activity.

Would London not have 20% of U.K. population to match its 20% of activity

We have enough evidence to show that companies will locate outside Dublin.
Cork has long been a strong location for pharma companies.
At least 3 of the top producers of replacement hip and knee joints have plants in the south west.
Galway has many med-tech multinationals, Sligo has a few.
Apple in Cork and formerly Dell in Limerick.

I have long felt that we are creating a bigger and bigger problem by allowing to grow dis-proportionally. We are heading for 35% of the population living within 1.3% of the land-space and many of these are living a poorer quality of life due to commuting times and housing prices.

Yes, companies will have a preference where they want to locate but they have only followed the narrative which we have created around Dublin being the only place to be in this country. We have been so busy trying to equate Dublin to London/Paris/New York that we are now caught in this circumstance.

Building a 2nd runway at Dublin while Cork and Shannon are vastly underutilised and people having to drive from beside these airports to get many flights is one thing the government could have but a stop to for the betterment of the wider country.
Every 'National' facility having to be located within eyesight of the spire is another.
The speed at which any discussion which thinks national policy should be in the interest of the wider country is called Dublin-bashing is a sign of how big a mess we are in as now, the number living in and very close by to Dublin is more than it can handle.
