I think that part-time job is difficult to combine with studying.
Student is often overloaded and he hasn't time for the learning. In my
opinion students should above all study. But, if sb must work - I
personally am admiring such students. Of course, combinating the work
with studios also has advantages.
Firstly - 'pocketful' of money.
Secondly, working students have rich CV.
Thirdly, they are developing their proffessional skills. Therefore, I
think that every student should work for example in holidays.
Moreover, the work is raising the self-confidence. I also think that
the majority of students working is supporting household budget.
On the other hand, studios are a unique moment during which students
have a chance to acquire the knowledge.
To sum I think that working and studying is possible, but one day the
working student can realize, that he missed studies...
