Yes and it would not be easy. But you would be doing it as an investment into the future and well-being of your kids. I have lived in Both ES and ARG. As someone mentioned it before, SP outperforms ARG on any health and psycho-social indicator of well-being. You would see this easily reflected in your daily living.
(I do not have children but if I did, and I had to start from zero to invest in their future and well-being, I would head to Scandinavia not Spain)
Out of curiosity: if you were to relocate, do you have a legal base for residing in Spain (you and/or your wife EU citizen?) or are you contemplating it hypothetically?
