Most migrants here don’t have a third level degree. Also higher levels of unemployment compared with Irish citizens.Ironically immigrants work and study harder and at lot of them are are encumbered with the need to get pissed every other night and are way more productive as they have ambitions after coming here in the first place.
Also consider that they are most likely to have more kids, will require more places in schools, hospitals and social supports. When you are importing 50k net new migrants a year it puts downward pressure on wages and increased demand for housing.
Ireland is a giant ponzi supporting the earliest entrants on the ladder. The minute FDI dries up, the stampede for the exist will be devastating. It’s developed zero industries of its own. 80% of tax receipts contributed from about 5 US multinationals. It’s going to be brutal.
