The presentation complains that the average salary is only about $11 an hour, but they says that bike tunes are priced low at $80. Considering that an $80 tune doesn't take more than an hour or two, maybe the discrepancy is between the money coming in and money trickling down to the mechanic.
Then again, the cold hard fact is that it's a simple job in a desirable industry that takes little to no training beyond what most serious riders have. How much are housekeepers paid? How much are grocery cashiers paid?
This doesn't seem to be a problem that's at all unique to the bike industry. The system itself is flawed, and thinking that bike mechanics are above it is foolish.

Electric bikes are lame, but they make a pretty sweet kid's bike though: http://grompatrol.com/kranked-ripper-hard-tail/
