I think there are a number of different questions, which don't necessarily have the same answer:
What could coaches do, at the grassroots level in hundreds of small rinks around the country, to develop skaters who have the basic techniques needed to move on to elite training?
What could elite coaches at training centers do to develop successful competitors starting from beginner levels for those lucky enough to live nearby when they start young or at middle levels when they decide to relocate or commit to long commutes, to develop elite competitors?
How can training for elite competition, and for recreational skating including competition, be made more affordable, accessible, and attractive to more potential skaters, especially those with skating-advantageous physical gifts?
What can US Figure Skating do to encourage coaches to develop these kinds of programs? (Given the fact that USFS has never directly overseen coaches or training methods and is not in a position to do so even if their membership and the PSA membership thought it would be a good idea if they did.)
It’s difficult to know but perhaps funding programs?
