Are concerts becoming too expensive?

In this part of the world in which we live have the average concert prices become too much for the average blue collar individual to afford or is it something else?  Are the lineups or packages worth the price?  Or is it as simple as a financial situation for people?  I know there was a time when you could see your favorite band for twenty five dollars or less but somewhere in our history, ticket prices became on average of $50 per person and when you figure in food, beverages and the possible t-shirt you could have taken a mini vacation, don't get me wrong I love concerts and seeing my favorite band perform live, it's when they are in their element and the amount of emotion that a band puts into their performance is stunning but I personally think that the pricing that has been set has become out of wack, it's like a lot of things in this world once the price goes up it never comes back down, there are of course those performers who understand this and charge according so that everyone can see their show, the two best examples of this are Kid Rock and country performer Garth Brooks who have both played shows where they offer very inexpensive tickets in that $25 dollar range which allows everyone to see their show and even have more money to purchase their merchandise which honestly will come back to them in the form of their merchandise anyway, mind you this is just my rambling opinion and I would love to hear yours
