When is outsourcing OK?

With all the brouhaha over the outsourcing of the USA Olympic uniforms I thought a discussion of outsourcing is overdue.

Yes outsourcing of jobs is ugly especially in the midst of a horrible recession when so many US citizens are out of work. But is there a time when outsourcing is not only OK but necessary? Are there some jobs that we simply need outside sources to get the job done??

Like we are sending US astronauts into space on Russian Space ships. Is this any less patriotic than Chinese assembled Olympic uniforms??

At what point does the outsourcing of jobs become a moot point and simply something that is part of getting the job done in the most economical and realistic fashion.
