Volunteer,
The reason your packs sales are low is because of the parents not wanting to do it, not because of unemployment or the prices. If the parents (and leaders, from the way it sounds) aren't willing to invest the time to help the boys, the boys won't be motivated to sell ANYTHING, and their sales will be low. I'm saying this from experience, as my son was the #3 seller in his Pack as a Tiger, #1 as a Wolf (beating our #2 by $1500), and is #1 as a Bear (beating our #2 by $2500). The only difference between my son and the boys who are #2 is parent involvement, plain and simple.
My son sets a goal for himself every year and I work to help him hit the goal. I do not sell for him. I go with him when he arranges his own Show & Sells and I sit thru the Show & Sell booths; I take him from door-to-door doing "Show & Deliver" and "Take Orders". I do not "have the time" - I make the time. I am a single mom who works full time. In addition, I own my business that I do on my own hours, and I have a 2 year old & a 2 month old.
The difference is encouragement, and the willingness to stretch yourself as a parent to help you son grow into a man. Period.
