It isn't simply accepted wisdom or opinion. Every fatal aircraft accident is investigated by the federal government until they find a root cause (and some non-fatal accidents). They don't just blame the pilot because it's convenient to blame the dead human either. Running out of fuel ranks near the top and is easy to verify. Failure to follow procedures is often a contributing factor if not a direct cause. Approach stalls are far too common, and that's simply pilot error - sorry, there's no other way to explain that. Mechanical failures happen too and are often a result of improper maintenance.

IMHO electric planes should be more reliable and easier on the pilot, but they may never really be a thing without a major breakthrough in batteries.
