Hummm do you know how expenive so called free education is in Ireland?
You know those lovely free colouring pencils/feltips/pencils/pens/highlighters/white board pens/personal white boards/head phones for the computer your UK school provides? That the Uk tax payer "picks up the tab for" Irish parents buy them for their child at the start of the year and are expected to keep replacing through out the year.
You know those lovely lovely exercise books that the school provide for free? Irish parents are expected to buy them over the summer holidays and send them covered and labeled in to school on the first day of the new year
You know those lovely texts books that the school magically update every few years? And texts to study in english?
Yes Irish parents are expected to buy them every year too (i know schools are increasinly moving towards book rental schemes but many schools still include text books and readers on their book lists)
You know that lovely free photocopying that allows your children to do worksheets or even being letters home? ...... oh yes irish parents pay for that at tge start of the year.
You know that lovely paint your kids use to nake pretty pictures to stick on your fridge..
Oh yes .....paid for by the irish parents too.
Plus the cost of school uniform, often even more logoed than in the uk, plus the not so "volentry contributions" that can be up to €400 in secondry school.
