Hold on. I’m not even sure what percentile this is referring to. It sounds like it has to be at least an 80th percentile salary among all electricians. If that’s the case, then 80% aren’t making $71k, so this sounds a lot worse than you make it out to be.

If you note here, there also seems to be cost of living adjustments just like you would find in tech centers as well, so California and New York averages seem higher. A lot of Electrical work is also unionized, so I don't know if that is a factor in any of this, but it seems like some tech workers seem to think unionization is better so there's that. The IBEW (http://www.ibew.org) for example seems to claim their workers on average make 37.69/hr which is right at 75k. The statistic is a bit outdated, but if anything it remained flat, if not slightly increased.
I still have to wonder how much of that is location dependent. $71k in most parts of the Midwest is quite comfortable. In the most expensive urban areas, it’s “livid with 5 roommates and never being able to save much” levels. It would be good if some of these stats were broken down by region, at least, if not MSA.
