a merger is usually a very good thing, if you own the corporation or at least part of it.
A merger is supposed to make a corporation more efficient. It reduces duplication of efforts, often referred to by cliche-spewing managers as "synergies".

The only time a merger doesn't work is if the two companies are poorly run (as in chrysler) or too different to combine well.

The merger of exxon and mobil was not a disaster for consumers. It had little or no effect on consumers. Period. the recent run up in prices had absolutely nothing to do with the merger.
I challenge you to provide any real evidence to the contrary.
