I don't know the opinion of the General
But I think for many salesmen it is just a case of sourcing the material for which there is a demand, be it range wrecks or containers stuffed with garden furniture coming from Indonesia. They think "buy low, sell high" - it is as simple as that. As long as they legally source the stuff they flog, there isn't anything wrong legally. Morally? Maybe....
I know some guys who have personally restored range wrecks - seeing how much money, time and other resources they spent, it could never have been a case of making money but a labour of love.
That my 2 Euro-cents worth, anyway...
