An expense is always someone else’s profit. All inflation, all prices, everywhere, is the result of someone putting up their prices, trying to make as much money as they can.<p>If it’s not the retailers, it’s the wholesalers, the suppliers, the utility providers, the lenders, the executives, the land-owners, the unions and even finally the workers. All of them trying to make as much money as they can. All of them raising their prices whenever (and if) they can.<p>Greed is not an explanation, because greed is everywhere in the supply chain, right down to the bottom. The question shouldn’t be why they wanted to (since why wouldn’t they?), but why they could.<p>Examining which part of the supply chain put their prices up seems pointless unless it sheds light on why that part of the supply chain in particular <i>could</i> put their prices up.
