And Norway - by far the most fun place out of the trio - isn't even in the EU so your work opportunities are limited if you plan on heading anywhere in the Union (you can open up a company though that will hire - you - as its director, so there is an easy loophole due to the EEA).
Citizens of EEA countries that are not in the EU (and also citizens of Switzerland) are able to work in and set up residence in other EU/EEA countries (and Switzerland) in the same way as EU citizens (albeit through different treaties and so on). There's no need, for example, for a Norwegian citizen to set up a company and be its director in order to work in, say, the UK or France.
