To put this into perspective, your grandfather fought in the Irish Civil War. Depending which side he fought on, he would have been perceived as unpatriotic by the other side.My grandfather fought in the war of independance and in the civil war.
He put his life at risk for this country, sacrificed his legal career and had to go "on the run" lived in the mountains being fed by locals.
What would he think if I move the bulk of my savings abroad.
Would I be spitting on his grave?
Should we stand and fight this economic battle or run for the hills?
So in a nutshell, look after yourself and your family first and foremost. If you come out of this on the greener side maybe you can lend a hand to those more unfortunate. That would be patriotic.
