@OP
I don't think anything has to be deleted. You had a genuine question. And people have given you answers. So now you have an idea of what people think.
I can think of one other member here who posts very basic opinions and questions that are actually legitimate. And if you didn't know the member you'd swear that he was yanking the chain. But he is not. It's who he is. It's how he expresses himself.
The moderator here is clear - back off with the insults. And I agree.
@thread
And now to answer the original question. I'm with Member Niding on this one. It ALL comes back to supply and demand. Grasp those concepts (as simple as it may seem on the surface) and you understand why anything is priced the way it is.
