There are unhappy people in every industry and in every position. But the game industry has surpassed the tipping point for popularity and 'glam' to make the detractors have enough social incentive/attention to be very vocal.
There are legitimate gripes, complaints and out right abuses in the game industry. But much of the brokenness in process or hours or management or etc also exists everywhere else. It is the unfortunate nature of a work environment. You do not read/hear about everywhere else as much fewer people are passionately following their output or dreaming of breaking in.
