The people that are intent on criticizing that group already has arguments for that, parents are concerned about getting free cars or apartments; TSL said something along those lines about Shcherbakova's parents regarding not caring about her career not being something long-term.
The fact that parents don't want a long career for their children in FS does not mean they just want free cars.
There is actually quite a lot of logic in not wanting a long career in figure skating:
1. Injuries are kind of cumulative. One thing is to skate on elite level for, lets say, 5 years. Another - 10, 15 and so on.
2. Injuries heal differently for different ages. One thing is to break an arm or a leg when you are 14-15, and another - when you are 25 or 35.
3. Competitive and even professional figure skating is not a life-long profession. Even with a long skating career, you will have to do something else when you are in your 30s.
4. Coaching is not a good job - yes, top level coaches make a lot of money, but those are a very small fraction of them all. I mean, if i would give career advice to someone, I would probably recommend something else.
5. Good universities and good degrees are kind of incompatible with competitive FS
6. Going to uni when you are 25 or 35 is not the same thing as doing the same when you are 18-20.
7. Long career in FS does not add money to what you got as kid.
8. And last but not least, someone has to pay for the FS. Russia has a very competitive field, so its not like government will pay for you forever (you get funding as long as you win), and sponsors will also not keep funding you for 10+ years after you stop winning. And this is not about "not training kids to have long careers", it is about tons of amazing skaters, and new even stronger skaters coming every year. I mean, what is the point to pay for coaching on top level, and neglect the education to have your now adult child go to a B competition 1-2 times a year? Sponsors or not, some russian skaters gave some insights on how much they make, and its not a lot at all. In fact, it was below the average wage. Its just not worth it, and not because the parents want their kid to bring them cars and apartments, but simply because no reasonable parent ever would want their kid to work for years for a low wage with 0 career prospects.
And so, I see nothing wrong that, if your kid is that much into competing, to have them skate while they are young, win everything, get a good foundation for their future life (an apartment and a car is actually a nice thing, not many 18 year olds have earner that already) and direct them to pursue other dreams. In fact, I would be strongly against a long career, specially in a field as competitive as russian.
In this regard, I find very interesting Kostornaia's POV in a recent interview, where she says she wants to compete for a couple more years, and then quit and pursuit medical career.
