I don't think that it is good for them in the following respects:
1)They can't really say what they want. They have agents, press secretaries, and of course, as far as anyone famous is concerned, the media is like the 'thought police,' overanalysing what they say and do.
2)They have to fly places on tour, they get fatigued, dehydrated, they might have to go without eating for a while because they are too tired to eat, they don't have time, etc.
3)They have relatives back home that don't get to see them for months at a time except for when they are on tour in their area, or they are on television or a music video channel.
4)Where are they going to get a decent education on tour. They can't have tutors and that's it. They actually need dedicated time in which to sit down and do some quality studying. Once they burn out as artists, they will have to play catchup in order to get a decent education.
The kids may want this at first, but then they will realise that what they got themselves into was a living hell.
