I just wouldn't have thought that it's helping. How can giving refugees and immigrants accomodation be helping a housing shortfall or the homeless? That doesn't compute on any level.
I see the argument raised they're in different parts of the country or whatever, but a government that is competent can then drive economic opportunities for Irish people to move to these less desirable parts where the houses exist and then the demand is lower where capacity is stretched. Creating jobs or the climate for job creation is another government function, and it's another way of coming at the problem.
The point is a an overall housing shortfall is present in the country and so is homelessness and people suffering in shit, mouldy housing. Just like in Britain. The priority really should be building more and getting people where they need to be, not trying to save the world and increasing the population further to add fuel to the problem. You're just never getting ahead of that problem with that strategy as much as it fits well in a liberal pamphlet.
