Furthering your comments, and those of others like Trippin, what do you think about the ability of an individual to avoid such manipulation? Can we all do it, or are some more prone than others?
There are a couple of things here:
1- At a basic level (think of an average NB)... it is really up to the program to have an attractive enough reward proposition that motivates behaviour.
Put another way - if the reward on offer is desirable enough - AND - you believe that it is realistically achievable you will alter your behaviour to pursue it. Same applies to any reward in life - could be the paycheck, winning a race, completing your degree, or chasing the hot chick at the bar.
Now it is a subjective assessment - so bothering to play the points game (getting a FF earning card, consolidating travel spend, engaging with program partners) may make sense for someone who is interested in free flights and believes they can earn enough points to score the free flight.
But programs like QFF can be their own worst enemy. We all know folks who believe that FFPs are a scam; that you can never redeem your points; that you can never earn enough points; etc etc.
Some of these people have never even tried to make a redemption - but they have heard enough stories - that they believe it's real. It's all about perception. Technically - it's called the availability heuristic - the same concept that lets us overestimate the chances of being eaten by a shark.
So for a non-status person - there is sorta a natural break on being suckered too much - in the sense that the minute you no longer believe that the reward is either achievable or desirable - you will stop pursuing it.
2- Now, for a regular flyer with status - it's an entirely different dynamic.
You have a lot of other issues, even ignoring the sunk cost of a substantial points balance (potentially).
You have both real and perceived switching costs (the Golden Handcuffs); and you also have a delayed impact of the reverse of the reinforcement concept we talked about earlier.
When the behaviour is no longer being rewarded - you'll eventually stop performing the behaviour. That's called extinction.
But it's not a switch - it's usually a gradual lessening of interest. (Except of course in the event of a significant service failure).
Think about if your employer stopped paying you. Kinda like that stapler dude in Office Space.... You keep going for a while - but at some point, when you no longer receive the benefits/treatment/love that made you loyal in the first place - you start to lose interest as the 'magic' has gone.
The next stage is more akin to being in an abusive relationship.
You still keep flying them, paying more than you should, defending them, forgiving service missteps, but eventually... it gets to a point where you can no longer be blind to the fact that you're in an abusive relationship and you should leave.
But it's scary for most people.
Where is the checkin desk for the other airline? Which terminal? Where is the lounge? How does PB work? HOw to choose the best seat? What's the etiquette and nuances that have become so second nature with your current airline?
#2 is quite strong for most flyers - if for no other reason than familiarity of habit.
Inertia is a much easier choice than change.
That's the true power of an FFP.
