From some of the blogs I've read, Nikon is far from being unprofitable. They make money with their various businesses and they sell a lot of cameras worldwide. Just not as many as they used to sell--like all the other camera makers. They're all up against a wall with products that are no longer "gotta haves", competition from smart phones and COVID... may as well throw in climate change, alien abduction, phases of the moon and every other cause imaginable, plausible and not. Just plain rotten luck all around.
Not sure those figures from Forbes are correct. Eighty percent of people over 75 pay no federal taxes? Of course you might think it's because they are retired but retirement benefits, Social Security and the like are all taxable these days. Every retiree I know is paying federal taxes on their retirement incomes.
