Perhaps but the great inflationary pressure on ticket prices beginning in the late 80s would never have been as severe if players salaries grew much slower and more reasonably.
Why is a new entry level car ~15 - 20k? In large part to the costs of production. Do you honestly believe costs have nothing to do with price - especially in this economy?
Depending on the product, costs may have nothing to do with price. Most of a hockey team's costs, including payroll costs, are fixed at the beginning of the season. From that point on, the marginal cost of an additional ticket sold is essentially zero, so the whole ticket goes toward profit.
This cost system is very different from the system involved in building an entry level car, where there are significant costs in materials and labour that go directly into the car.
A business where all costs are fixed (and a hockey team is pretty close) doesn't need to consider the cost when setting prices. They set prices only to maximize revenue.
Rising ticket prices in hockey were entirely driven by the rise in disposable income available to spend on entertainment that took place over the last three decades. It's not just hockey tickets that rose in price - every major sport's tickets rose in price, as well as rock concerts and all other forms of entertainment. People were willing to spend more money on sports and entertainment, and this drove the price up.
If hockey teams cut salaries and lowered the price of tickets, tickets would be rationed by lineups instead of price. More people would have the possibility to go to games, so you would have lineups as soon as the tickets came on sale, whether on the phone or online. Teams would be leaving a lot of money on the table to allow this to happen. What possible reason would they have to do so? Growing expected future revenues is one reason, but you can't allow current revenues to drop too far in doing so. It's just bad business.
