Question from an American Nursing Student?

I am an American sophomore nursing student with an Irish passport and I can move to the UK or Ireland when I graduate because America is lighting itself on fire. I want to move to the UK or Ireland but I don't know how I will live on a low salary for nurses. Is most Nursing Salaries there low or is that just NHS? Are there good private hospitals that pay a livable nursing salary or should I just stay in NY? I know this is two years out but I want to think ahead. I don't care where I work as long as I don't need a car.
