I don't know much about VFX but that's certainly true in much of the scuba diving industry. They find young people who love to dive and want to make it a career, and sucker them into paying for training to become dive masters and instructors. Then those people get stuck working long hours for miniscule wages, always under constant pressure to cut corners on safety while trying to sell more equipment and training courses to customers. There are good dive shops and instructors who don't play that game but they are a minority.

In general be cautious about getting into any industry where people are there more for love than for money. That tends to create exploitive situations.
