Sorry, but you're way off with that observation.
When the Academy system was revamped, Bees were one of (I think) only two Lge One clubs to achieve the highest grade of Academy. They spent a fortune on facilities and top coaches, inc a tie-in with a local college for whom they built a big sports centre etc. Thereafter it was costing over £1m a year to run, but early results were v.promising.
But then, after the PL bunged the FL some money, the latter agreed to change the rules for youth players which meant PL clubs could now recruit the best kids developed in other clubs' Academies without having to pay proper compensation. Bees suddenly lost two of their most promising youngsters, on whom they'd spent serious time and money developing, to Man City and Man U, for £30k each - "licensed robbery".
So in response, Bees cut their losses, closed the Academy and initiated a brand new concept they call their "B" team (pun not intended), whereby they signed up top young 17-22 y.o.'s from all over Europe who hadn't quite made it in their own Academies, so as to give them a second chance (late developers or overlooked etc). This "B" team plays prestige challenge matches, home and away, against teams like Bayern, Benfica, Inter etc, as well as Chelsea, Man City and other top British teams.
And it has been very successful in producing players for the 1st team, helping lads through that difficult period between Academy football and senior football. Indeed other clubs are now copying the concept, eg Huddersfield.
