I mostly agree with you. Even in my disagreement, I agree with part of your comment. You say that a person who traded when they bought doesn't know their true price. In many cases that's true, but in mine and some others (I assume), I had fully negotiated the new truck price and agreed on that price prior to discussing a trade. I was willing and committed to buying that truck even if I decided not to trade my truck on the purchase.
In the end, I traded my truck in, but I am VERY confident in knowing my true price paid for my new RAM.
The generalization you made is quite condescending. Your statement might be true with the general public, but in a forum group (who tend to be enthusiasts and/or otherwise more detail oriented than the general public) I think you're making too broad of an assumption.
