Re: It's the Circle of Shite.
It's exactly the same situation in the animation studios. Loads of disposable youngsters willing to work long hours, with more behind them to take over when they get worn out.
The studio will promise a fast turnaround and low costs to beat other studios and get the jobs in, then the animators have no choice but to get the work done to almost impossible timescales or leave. There's no union to help, so if you complain, you're out as there's always someone foolhardy and desperate to take your place. The only people who survive are those without partners or kids who can keep up. Eventually age gets to them when they can't handle the long hours any more.
