The key part is that the parents had to mortgage their house twice. That's a huge sacrifice. There were other financial sacrifices too. There is a financial access issue for the elite level. The sacrifice is similar. I tend to go the scenic route in making my points. It's also not worth the financial sacrifice if you will never in a million years make it internationally, let alone to the Olympics.
If you would actually read this thread and the points I have made very clearly throughout from an elite level perspective, you'd know that I mentioned about skaters parents including my own who mortgaged their home a few times to get me/them what was needed to succeed. It's kind of ridiculous to think that some 5 year old in learn to skate has a parent doing that, because they probably don't. This is potential elite and elite with that mindset. If the parent does it any a much lower level then it's on them.
