unfortunately in my view the EFL and the associated bodies don't really care about those broken dreams, it is all about the individual clubs. A possible approach is that L1 and L2 clubs don't have academies or youth systems, but they all contribute the same % of revenue (or another number) to regional academies. The infrastructure of those academies (set up using the UEFA academy designs) is funded via a % from the Premier league, smaller % from the championship, % from parachute payments, % from the FA and a % built into TV deals for the EFL. These regional academies cover both men and womens football and there is a draft model similar to US sport for those that graduate to enter the EFL. Any sell on deals money goes to the first club and a % to the regional academy.
Just an idea
