Far Away hills are Green.... you may be paying TAX at high rates in Ireland. Other countries make you pay tax as well.
I get a higher Take home wage in The USA but I also pay a hell of a lot more for many of the things that you listed there.
Health Care, Property Tax, etc etc.
OK VRT is non-existant and road tax where I am is $110 a year for a 5.7 ltr hemi Truck.
Ireland is a pain tax wise, but other countries are no better.
You will work all your life in Ireland, possibly have children or not, but if you want to give whatever you saved to your heir they will pay 33%, in the US and other countries they would pay zero.
