No immediate profit center. All the major studios are in California, in places like LA, which cost of living is astronomical. Those positions are jealously guarded and getting hired is based more on who you know rather than what you know. If you're a nobody, you can't afford to live in LA long enough to land a solid job as an animator.
And you have no profitable options as an indie animator, either. YouTube changed its algorithm so you cannot possibly earn a living through ad revenue. You can have a dayjob and animate on the side, but since animation is so tremendously time consuming, you'd never be able to produce enough content to make any of it worthwhile.
So that's why there is next to no motivation for people to learn the craft of animation and become proficient at it.
