From the story here, which never once mentions the problem of declining product quality:
It’s a bad day for a CEO when he announces he’s retiring and the stock goes up. That was Jeff Immelt’s day on June 12, 2017. ... Its bonds, rated triple-A when Immelt became chief, are now rated five tiers lower at A2 and trade at prices more consistent with a Baa rating, one notch above junk.
Did Immelt run GE into the ground?
Look no further than its light bulb business. While GE-branded lightbulbs shifted to compact-fluorescent technology and then to LED with big promises of longevity which never panned out (trust me, I have BAGS FULL of expensive, failed examples of each), it somehow stopped knowing how to make incandescent lightbulbs which worked, too.
I discovered this with its appliance bulbs. A couple of years ago I had to replace an oven bulb after a few years of service from the original one. None of the GE replacement bulbs lasted more than a day. When I went online I discovered the problem wasn't mine alone. Customers all over the country were having the same problem.
I've had a similar experience with another GE appliance component: gas oven igniters. The OEM part lasted just six years. The OEM replacement? Less than two.
Additionally, GE's long-term care insurance business appears to be tracking the same history. It sold off some of that business not long after 911, and what business it has kept in that line has been in the (bad) news lately as well. GE over-promised on some plans it issued and undercharged for them, not realizing that claims would exceed expectations, making the plans unprofitable. I'm sure that's unsettling to policy holders who trusted GE. How long before the long-term care plans of older customers stop working altogether?
And is it just a coincidence that the Fukushima nuclear reactors were of GE design?
Yeah, sure. Just a coincidence.
