Do you understand the meaning of partially and temporary? Furthermore I do not "blame", I'm just sharing my view on possible causes for our "problem".
Prices are always the result of supply and demand. Telling people to stop overbidding is not solving any cause, just the symptoms of the fact that we have more demand than supply (though I personally don't think it's smart, as you point out not everyone has time or wants to wait for a good deal). As long as there is demand for players and we have enough money around to make such high bids, it will happen. This last point also is part of why what we see might not really be a problem, because if we all have more money available, it's no problem if player prices are higher. It's called inflation, plus the fact that if you sell your player you also get more money, which negates the higher price you need to pay for new players.
It's like selling a house during economic breakdown; people don't want to sell their house for less than they bought it for, not realizing they also pay less money for a new house that was worth more before.
