I just asked, seriously, what's "reasonable"?
Collusion and "price fixing" are illegal, and that's a serious accusation, which is usually unfounded. For one thing, it gives way too much credit to the parties involved, i.e. that they are smart enough and coordinated enough to actually attempt it, much less pull it off and get away with it. It's one thing (and legal) to see what others are charging and adjust your prices accordingly, but quite another to conspire with competitors to mutually fix prices. I don't believe that's happening here. And "contrived shortages" are not a necessarily a sin, a producer has the right to cut back production when there's an economic incentive to do so, or to divert production to certain products for which there is a higher demand and profit, for example filling military ammo contracts ahead of making consumer products.
