Oh my lord. Where do I start?
Mara, many people post situations without revealing the details, and it appears to me to be the case here. Whenever someone says that security was called, with no indication as to why, little alarm bells start ringing. Almost always it turns out that the poster threw a tantrum. What was the story here? (for the record I travel almost permanently drunk, yet have never managed to attract the need for security in over a 1000 flights)
As far as only one upgrade, I am understanding you mean a freebie? Not a points upgrade. Let me get you back down to earth on that point, as you no doubt have been misled by "frequent flyer" hype. I am P1 with Qantas. Do between 100 and 200 flights a year. (not bragging - just setting the background) I think I have had two upgrades in the last 5 years. Forget the notion of freebie upgrades - they are so rare as to not warrant even hopeful contemplation!
In your post you refer to "those sitting around us paid less for the ticket", "were not frequent flyers", and that they were "in their early 20's". How do you know they paid less, and what does that matter? And how do you know they were not frequent flyers?? And as for their age, what on earth does that matter?
You include the detail that you have "post tertiary education". With an exclamation mark! Unfortunately for you, that perceived value to your life only matters amongst other academic persons. Unfortunately for you and your situation, some of the most ridiculous tantrums in aviation history have been made by academics who for some bizarre reason think that their life choices and achievements in their small field somehow make them better than others. That is a notion that, I repeat, only holds true within that tiny circle of said academics.
Last comment, with "at least one overseas trip, sometimes 2 a year and several interstate trips' you feel you are a "frequent flyer". And you are, compared to many 20 year olds with no tertiary education. But in the big pond of world travel, that is not actually much in this day and age.
Sorry to be so confrontative, but hopefully these comments may help you reappraise your reality, and so hurt less
