Not necessarily. There is a certain optimal point of price and demand. It's entirely possible that the limited supply due to all the barriers to entry allows even a range of competitors to price their products well above their own costs or the minimal costs in their industry. It's just not true that multiple competitors have to collude to keep prices well above the perceived minimum costs. Or that collusion is a conscious process, either.
