Does America have a worship problem?

I've just started a new book, Experience God in Worship, which walks through several different styles of worship by a number of different authors. I'm only 16 pages into the book, and reading a section written by George Barna full of statistics about the church and worship. I came upon a quote I thought was worth posting here.

"The notion that America has a major problem in the area of worship is an inescapable conclusion. Perhaps the most striking feature of the research is the revelation that our problem is not an inability to craft services or experiences that are culturally relevant--we know how to do that, although many churches still resist doing so. The problem is that American Christians do not have a heart that is thirsting for an experience with God, eager to express gratitude and praise to Him, and open to His response to their efforts to convey humility, appreciation, acknowledgment of His love and character, and joy in knowing and serving Him." (George Barna in Experiencing God in Worship)

What do you think? Does America have a worship problem? Do you agree? If so, what is the solution?
