Wow is a million dollars typically what a parent in the US will spend?
When you consider she started at 5 and that's 15 years of skating now, and Alysa's father mentioned taking her "everywhere" from Japan to Canada, it's actually quite unsurprising.
In the transcript it's clear her father was even more passionate about this than her for a while.
If you consider private coaching, choreographers, off-ice practices (e.g. dance), travel costs & miscellaneous (skates, programs, physiotherapy & medical, costumes (one costume can easily cost 4 figures of which she needs at least 2 per season not including exhibitions, same for programs)) around 40k/yr is likely on the low end.
The transcript says he spent half a million to a million so if we take 750k and put it over 15 years (her career) that's 50k/year. A little higher likely since she took a break, perhaps less at the beginning then more as she became professional.
The average parent of a national team member is not spending much less. Of course the hobbyist won't be spending like this.
Something else nobody has mentioned though is how much she has probably made (and will make) in return. I would imagine it's 6 figures at least by now. Her career is peaking she could be making 4 figures monthly on social media alone (not including large deals & appearances). I'm sure Ilia's career has costed 7 figures but it will be worth at least that in the end. So this all isn't as crazy when you consider parents also spend a solid 6 figures on regular schooling.
