Isn't this in the heart of consumerism... how to offer enough but not too much options, and how to keep consumers just the right amount unhappy so that they keep consuming and how to keep giving examples of everything they could achieve by it...
But really, I think this is very common. I'd be more interested in reading about
why people behave this way, not to hear how they are failures in this way... I wonder if study asked about the financial background of the people they researched? We live in a competitive and materialistic society, and it blames individuals about many things they really can't do much about, like being laid off from your job because "the economy is bad" and not being able to get a new job right away, or not being able to keep the job at the first place. At that point it's difficult not to feel unhappy with the life choices you made, like what you studied and where you applied a job from etc... people try to make the "right" decisions all the time and naturally that's impossible, but if you are trying to make your life better, get some money and stability, that doesn't offer much comfort. The atmosphere of constant insecurity at work places feeds this kind of behaviour, if you are constantly reminded that you are easily replaced, constant evaluations and reminders to do better, all the stuff that is so common today.
It's often the same in private life, you're supposed to be successful, meaning you have all the things you're supposed to have or else you are a failure. It's easy to cast off things, relationships, what ever it is that makes you feel like you are not living in the standards you "should" be living if you're orientated this way.
I have to admit I'm a "maximizer" too when it comes to some things in my life, work mostly, and that's a thing I'm trying to change. Less stress, even though I might not be doing things the way I always thought I'd be doing
Many people are doing the same it seems, since I've read news about employers and even governments being unhappy with people who don't want to work like a horse all their life and benefit the society and the employer... many choose to do something nice and live with less. Very positive, in my opinion.
