Yes some interesting names added in there to be fair, although I'm not sure how many have played 50 league games for said team (which I see as a bit of a litmus test).
I think it's broadly similar over long periods, but we have made a bit of a mess over the last 5 years or so. I would also say if you are counting Bellerin, you should probably have to count Stones, Holgate, DCL etc who would likely be sold for 150m+ ish combined (hence why I avoided lads bought in as late teenagers).
I think the loan thing is a big of a misnomer. For a starting point most of the lads above went on loan and didn't progress. We don't have the brand or the quality of team to end up enticing teams to want to take players on loan in the way they do. We are not CL regulars. Our solution has to be that we are braver in giving opportunities to players in our 1st team, and not having them on the loan conveyor belt. Partly as it will help them get loans, but also could they do better than what we have. Are we going to be brave enough to give game time to Gordon and Brainthwaite this season for example? Maybe even Lewis Gibson. I'm not a big fan of Simms but there's probably a case for him too.
That is what German, Dutch, French, Italian etc teams are offering to younger players. A chance to play regularly, for a team where you have a 3-4 year contract. To me that has to start becoming the mindset. We loaned out most of the Ledson age group and it didn't work out well (albeit they got a fee for Robinson too).
I am still not sure why certain young players were not on the bench for fixtures last season, that felt a mistake to me when the spots were left empty.
