Ireland thankfully opened its doors to take in war refugees from Ukraine and the response from Irish people has been fantastic, but this could run for years.
We are a rich country partly because multi-nationals are attracted here by low corporation taxes and the space provided for “tax efficiency”. Now we are in an emergency and those who can afford to pay more tax should do so.
