I agree on the lack of appreciation and meaning, but the problem is more fundamental than good or bad bosses: the problem is that "bosses" rarely are a needed part of the process at all. A good boss can minimize the damage they do, but in the end, most bosses are just middlemen between producers of value and consumers of value, a position which allows them to siphon off value without providing any value themselves. Giving someone who provides no value decision making power over people who provide value is always going to result in the person who provides no value overvaluing themselves. It's no surprise that many people feel undervalued, because inherently bosses are overvalued.
That's why I said that even the best bosses can only do so much to make jobs that require convincing people to buy stuff you know they don't need seem meaningful. The reason I linked that article wasn't the bosses who I agree are not the essential ingredient, but the other part, which is why I also have that last paragraph: It does not seem to be the work (load) that is the main cause. I added an edit to the comment, thanks for pointing out the possible misunderstanding of where the focus lies.
