Mergers and acquisitions

Last year, the publisher I work for merged with another publisher, and then this week I found out that the company I work for at my "real" job is going to be merging with one of their competitors.  I suppose this is just the nature of the economic world we live in, but I have to wonder if all of these mergers will cut down on competition throughout the business world.
The funny thing about this is that it sort of plays into the novel I'm thinking about writing...one in which the elimination of competition in the corporate world has some grim consequences.  Yes, it's a dystopia...
