What do you mean by this? Are you saying younger folks don't understand or are greedy/will flip but older folks won't? Being greedy is not a new fad, it's been around longer than us..greed does not grow inside the mind of either the young or old, it doesn't discriminate. It is cultivated in the minds of the selfish which, in my opinion, see themselves as above everyone else. Greedy people come in all colours, shapes, sizes and ages
That aside and more on flipping for a profit; the only way to combat this is for the maker to increase the price, they deserve the money anyway. The way I see it is that they are short changing themself, no matter their good intentions, people will take advantage of what they can. We may not like it but that's human nature and that is what got us to this crazy world we now live in...
I've flipped a knife or two before but only if I genuinely needed the money (cough, who doesn't noawadays, cough). Does that make me greedy/whatever you wish to label me as? Maybe. I've also sold many knives at and under cost. Does that make me selfless/whatever you wish to label me as? Maybe! I think it all balances out in the end for the regular folk...
I wish the ones that only buy knives to flip would take their "business sense" elsewhere from our community but the way it is now, there are no rules in place to stop them and me and you cannot do anything but complain so instead I just move on with my day.
