My point was not that investing 40k weekly is bad in all cases, I just warned that it's not good advice for every situation. Yes, if you really must have the highest potential highly skilled homegrown player, then it might be a good way to go, but the question was asked by a starting manager, and that might not be his goal. I was saying his money at that point is better spent elsewhere, like in the Arena while keeping scouting costs lower and not try for the jackpot every season.
The problem with many helpers here is that they give advice for their own situation, we need to take into account the situation of the question asker more often.
