The situation you've described is one of simple supply and demand economics. It is a push-pull relationship. If supply decreases without a corresponding drop in demand, generally the price will rise. If supply remains in sync with demand and the price rises, it is due to other factors usually associated with rising costs of production and transportation charges. A third factor, of course, is now taxes. If taxes increase, it cuts into net profit. These net profits are not simply pocketed. They are used to put back into the business for future production, modernization and expansion.
If, on the other hand, you are talking about price gouging, the free market will take care of it. If the price is too high, fewer people will buy or will buy less often. This again will cut into profits at some point and the price will stabilize or drop. Either that or efficiencies in production will make it possible to cut the price and simply produce more product at a lesser margin making up the difference on volume.
One must understand that all of these factors are interdependant. If you want a better idea, check with the Chicago Mercantile Exchange. This is a commodity futures exchange. You can monitor the price of Pork Bellies (bacon) for delivery prices well into next year. They may show a steady rise. Just remember, it can change due to any factor. So keep watching if you are truly interested.
