We're a football club, and football clubs cost money to run.
We can't, and shouldn't, moan about the youth set up costing us money to run. The first team costs a lot of money to run too. Should we scrap that too?
There is more to the club than just the first team.
Plus, if we scrap it and then in 2 years time we realised that was a massive mistake, it will be ridiculously hard to re-establish a youth set up from scratch.
