I don't think there will be much problems. It may take some time to adapt plus struggles with language & system differences. But I feel life style there is happier. I have been there for vacation and felt like -- general life is way laid back than in USA. Working hrs is lesser than in USA say 36-38 hrs per week. Grocery is way healthier and cheaper. They might have less pay check though. But since your family is moving and u don't need to worry about immigration status. You should do fine with time.
