It is frequently mentioned that PhD students are employed in Europe (e.g. the Netherlands, Scandinavia, etc). I still don't understand how this affects a PhD program.
What is the difference when one enrols as a PhD student in the US or has a work contract in the Netherlands? Is there any specific difference in responsibilities, expectations, freedom, etc?
Please make a tangible comparison rather than listing various possibilities. If a student enrols in a PhD program in the US or in the Netherlands, how will their work and life be different?
