Pretty much. I mean, there's different levels of inherent; there are basic physiological and psychological needs, and then there's needs like my need of some kind of a solution that would let me get all of my monitors further away so that it's easier on my eyes to sit in front of them all day, whether that's a bigger desk or some kind of a stand or something, which I would also count as an inherent need in this context even though I didn't have it until I got a third monitor which made it less trivial to fit them all on my desk. It's still a problem that I have and would like to have solved, and getting rid of the third monitor is not a solution I would be happy with because having three monitors rocks. Possibly a company could start developing a new product that's designed for people who want to have their monitors further away, and later also have a huge advertising campaign targeting the people who haven't yet taken into consideration that it's pretty important to have your monitors far away from your eyes, but it would only have any hopes of working out because it legitimately
is important, so some of the people seeing those ads could potentially be convinced.
Now, if the same company also sold third monitors to people who previously were able to have both of their monitors far away enough just fine in an effort to cause them to run short of desk space and thereby have this problem that their product conveniently solves, that would be pretty clever of them, and it could result in a sequence of events that starts with a person who does not want a Monitorfurtherer and ends with the same person happily buying one. However, at every point within this sequence, the person is only buying a product they need because of their current circumstances, and what the company is manipulating is the circumstances, not the needs directly. This is similar to the women's shaving example, although pushing a cultural shift to make women's armpit hair seem undesirable was a much more impressive feat than selling someone a third monitor.
(And based on the
Wikipedia article, I'm getting the picture that it was basically an amazing once-in-a-lifetime opportunity that Gillette and other companies were there to seize at the right time, since it was a time period where the previously established ideas about femininity were getting outdated, which I assume must have created somewhat of a gender expression vacuum where many women would have been actively looking for new ways to express their femininity, and a few other trends were simultaneously going in a direction that made the armpit hair removal thing seem like it made sense. As far as I can tell, it is not typical for companies to have done something like this on a comparable scale.
And also I shave my armpits too, I do it because it makes my body feel more like my body, a more harmonious existence in a way, but I didn't start doing it until I was reasonably sure that it was established enough for men that I could do it without feeling like it contradicts my gender expression. I'm fine with, and perhaps even happy about being an early adopter when it comes to new trends for masculinity, but being at the frontlines trying to set the trends myself is a bit too much for me. So I wouldn't be terribly surprised if some women in the early 1900s were likewise excited about this cultural trend, but I doubt there's any way to find out if that was a common experience or if it was more common to shave just to fit in while not particularly enjoying it.)
The fashion thing doesn't seem as forceful to me, it probably happens on its own that the trendy thing to do is to copy whatever the highest-status individuals are doing as early as possible, and the later to the party you are, the less cool it is, and at some point it gets so lame that the original high-status individual who set the trend abandons it and starts doing something new. There is therefore a need for "newly designed clothes", and that's the product that fashion companies offer, the exact designs aren't that important (although it probably helps if they're legitimately good designs) but the novelty is.
