I don't know what countries becuse even in USA or Canada they usually start at the same age (4-5), the same with most european countries I'm aware of, incl. Italy, Austria and my own, not to speak about Japan and South Korea, but if there are such, it's the cause of those countries, not the international rules.
And I simply don't think there is anything requiring to be fixed now. The only thing that was wrong was when the medals were split between someone's "long-term queens" before the competition has even started and that times are gone, thanks Darwin.
I was thinking it more from a financial standpoint. In many cases the federation doesn't cover all the costs, the family needs to pay and FS is not a cheap sport.
You need the investment to afford such training regime, yes in Europe and US they also start to skate early (that's actually not always true though) but most skaters learn their triple jumps and 3-3 later, also because they just don't train all that much at that early age. You can see it in juniors too, very few have their 3-3 done and ready at the age of 13.
Skaters like Alysa Liu are very much an exception rather than the norm.
