It's alright and quite frankly understandable to be motivated to work on a "big project with big cash and big name".
The problem is when the producers use it in an exploitative way to have people work insanely longer hours than billed, or to lower the costs of labour so that the workers can have the "pride" of writing "big name" on their resume.

Unfortunately, this is common practice.
