I haven't thought through the logistics as it would need some serious work beyond my meagre intellect, but I stand by the notion that sorting out some kind of pay for the training on a national basis would give a platform for reform and the only real way to empower a governing body to impose structure. Once that's in place you can start delivering a progressive way to assess & stream athletes within the clubs or even between clubs where appropriate for the athlete's development, possibly without the seed club losing 'ownership'
With regards to putting less well off athletes by increasing the subs I understand the point and think it would be a bit of a jolt for current athletes, but I doubt the fallout would be too damaging as long as the benefits were outlined properly and of course ongoing it would just be the norm.
Let's face it, I cant imagine there are many parents or athletes who havent scratched their heads wondering why the coaching is not more expensive anyway.
Tennis lessons - £25ph, football training £5ph, athletics..... £3 for 1.5hrs training seems an absolute bargain in my opinion.
