Well, according to the topic "Balance in the market " there is a balance. People, managers, WE create the market. If someone sends his player to transfer market for 1M starting price and there is a bid during 3 days it means it was a fair price, because other position see some profits of that price. Prices dropped seasons ago due to growth of new managers. I started playing BB since season 10 and there are more managers now. It means more money, and even more players. Well trained players also dropped at their price. Check how looks like B3 final in season 10. My team looks better season ago in Div.3 than B3 champion then. What it suppose to mean? There are more well-trained players. When supply rises and demand stays on their level than prices have to drop. Typical economic rule. I think prices will drop even more in closest seasons.
Another reason why prices have dropped is team's financial balance. In first BB seasons, teams look like they were earning 2-4 millions per season (top teams). Nowadays, perhaps it's 1 million average for developed countries like Spain, Poland, Italy, Turkey etc. Teams spend more on their salary = less money on the market. Teams in lower divisions make of course less money per season.
Both factors affected that draftees cost more (I would add also national team factor, which is associated to prestige what makes perfect draftees some kind of luxury good). It's sound irresponsible that managers pays more for 18yo 5k draftee than 26yo 100k player. However nobody says that investors make proper decisions :) I think people don't know especially what they do. If i spend 1M i have to see some profits due to that decision. Managers spend 3M on draftee and will never see a profit. Firstly, they won't cap him. Secondly they won't buy any other player.
Market is balanced, but participants are just stupid (not all of course). Your decision is how to make an advantage for yourself due to that situation. After some time managers will see that they pay too much on draftee and will buy those trained 26you players. Then, you should train players, because when supply falls then price goes up. That's the clue.
Even on stock market you can see irresponsible participants which hold their stocks when price goes down. Just 10% make profit:)
