Automation increases jobs.
Automation does require the displaced employee to get another job. This may require retraining, returning to school to upgrade or acquire a skill set that is marketable. The may require a change of career. Most displaced employees will find other jobs.
Imagine the Chinese, Indian etc workers as robots. Have all the US workers who've lost their jobs to these "robots" experienced the increased number of jobs you mention? Now imagine what happens when Foxconn et all replace those Chinese workers with real robots (as Foxconn is actually doing).
What will these Chinese workers do? Some of them will take your higher end jobs: http://www.npr.org/blogs/thetw...
From the article:
And it turns out that the job done in China was above par â" the employee's "code was clean, well written, and submitted in a timely fashion. Quarter after quarter, his performance review noted him as the best developer in the building,"
If the population growth remains at X% and the Earth resource/wealth extraction rate does not increase by much more than X% if robots and automation take some human jobs, there will NOT be replacement jobs that pay out the same amount of wealth. Because in most cases automation is about reducing costs and increasing profits. Furthermore the resource extraction rate cannot continue increasing as long as we are stuck on Earth.

tldr; the automobile destroyed the jobs of the horses, there was no increase in replacement jobs that the horses could do.
And that is what will happen to most humans once the robots get good enough.
 Many of these workers are actually doing jobs that are "robotic" and could be automated- it's just that they are cheaper and more flexible than current robots and someone else paid for much of the manufacturing).
