Is it typical to work 60 hours per week as a PhD student?
The experience of working long hours, for little pay and little power is, unfortunately, an almost universal experience for science PhD students around the world. In the UK and many other countries PhD students are not considered employees at all, and so have no contract of any kind - they are not paid a salary, but a stipend (i.e. a grant to allow them to live).
The situation is difficult because even if you have a good supervisor, there is still a minimum amount that is needed to pass a PhD (which is outside the supervisors control), often a maximum time limit to complete it (also outside the control of the supervisor), and more often than not, a the stipend/salary paid to the student is also outside the control fo the supervisor.
However 60 hours a week is not normal for the simple reason that very few people can be productive for 60 hours a week on a long term basis. So a supervisor that demands this is not only exploiting the student, but also mostly likely not getting good science out of it either. We all have to work 60 hours a week occasionally (and that goes for pretty much any professional job), but as a basic expectation it is in no ones interests.
EDIT:
To clarify the above - I both think working 60 hours a week is unhealthy and unproductive AND that is is less common than people think it is. Long hours, yes. But 60 hours is more than people realize it is, and few students I have known work 60 hours a week, week in, week out for years on end. Not no one, but definitely not &quot;typical&quot; as the question asked.
