I believe you are correct in some of what you say. The Asians have suffered right along with the rest of the world in this current economic down turn. However I also believe the end user you described will have more purchasing power later when things get back on track, if in fact they do. China, where I believe most of the end users you speak of are located, was in full swing last year with a booming economy. They are at a good position to take off economically again if the economy turns around.
Something else to consider, is that the seller can ask whatever price they want, and the buyer can offer any payment he is willing to pay. If they can't come to an agreement,no sale. There is lots of tame bed raised ginseng out there at $15.00 per pound, if they do not want to buy the wild grown. If you expect to buy a Mercedes, you can't expect to pay for a pinto.
