I'll Tell You What is Causing Pain for Almost Everyone in the Western World

There's the muscle sheaths that have stiffened by the lack of use of the full range of motion and the constant deposition of collagen, which literally glues the sheath to itself. This tight sheath can impair blood flow to a muscle, especially when the muscle is contracted for a long time. The contracting muscle presses out against a tight sheath. Blood takes the path of least resistance.
That lack of healthy blood flow can cause the sarcomeres, the contractile unit of muscle, to get stuck in their contracted position. This is how a muscle gets tight and actually shorter.
When a muscle gets very stiff, a trigger point can develop. A trigger point is just an area where many sarcomeres are tight. We certainly notice trigger points, but the muscle gradually hardens for a while before a trigger point develops.
The hard muscles are shorter and thicker and this makes manipulating the sheath to break up the collagen much harder. But if the muscle is softened first, it can be done.
Massage is how you soften the muscle and get the sarcomeres in it functioning again. Massage pushes depleted blood out and then new blood is pulled in from the capillaries.
But there's still one other factor and that is the way muscles communicate with each other to accomplish work. When one muscle is engaged, other muscles receive nerve signals to help. And if there is a trigger point in one muscle, other muscles are engaged via the nerves.
When trying to sit for a long time, tight muscles may be pulling you in one direction, requiring other muscles to have to work constantly to keep you upright. This is why maintaining a natural posture can be difficult. It ought to be something you don't have to struggle to do.
So you may have a tense muscles but it may be another muscle that is the root cause. All of the muscles need to considered and massaged in a systematic way.
Excellent point... "Stand-up straight" as advice is simply too simple.
Still, I think your good advice from Trigger Point therapy should be supplemented with some information from the Alexander technique.
You see, original article begin correctly in saying that "bones don't get tired, muscle get tired". If someone could stand or sit without muscular tension, they could avoid getting or aggravating trigger points.
BUT....
It's just that at point of being in distress, people just don't know how to do that. And there really isn't an easy instruction set that will tell most people how to do that because... trigger points and habitual misalignment causes people's sense of their bodily position itself to be distorted. Specifically, when your muscle is habitually shorted, it "feels" to the person like that muscle where it should be. So a person who say is told to "straighten their back" will do by tensing another muscle to fight against their habitually shortened muscle. And so in practice, as you observe, "posture doesn't help".
Still solution to people's misuse of themselves also has include something like a "hands-on retraining" of the body so the muscles and nerve learn together what "upright" actually means.
I'd link to Wikipedia on the Alexander technique but the article has gotten so crufty it's an embarrassment... Still, retraining of "use of the self" is an important compliment to any massage.
It shows a couple of videos and mentions the Gokhale Method http://www.egwellness.com/gokhale-method and Ageless Spine by Kathleen Porter http://www.agelessspine.com/book.htm also links to previous posts with further discussion like the Asian squat, and images/videos

This is simply incorrect, as are most of the conclusions that follow from it. Basically, many muscles can trade off individual contractile fibers to remain under tension all day without perceived tiredness.
You are not a stack of blocks and you can hurt yourself by pretending that you are. Your body includes tensile as well as compressive structures and the whole thing is tied together with a control system. You are not meant to stand up without reflex muscle contraction! (You also aren't meant to sit or stand in one position for very long, but that's a longer discussion).
I trained as an Alexander Technique Teacher, but for the technically inclined I'd recommend reading Moshe Feldenkrais's Awareness Through Movement as an antidote to this way of thinking. See Understanding Balance by Tristan Roberts for more detailed information about postural reflexes.

What's really needed are ways to undo the rigidity. No doubt there are a variety of these. The most effective I've found is the Alexander Technique, an early 20th century form of bodywork that remains modestly widespread, i.e. it's not that popular but you can find teachers in most major cities. It's a curious, very gentle and non-invasive practice that is somewhat counterintuitive but in the hands of a good teacher (I tried three, only one of whom was good) delivers lasting results. I recommend it to anyone who likes to explore this kind of thing.
One day in class I particularly remember, prof Henes brought a balance board (one of those round boards on a ball) and asked us to balance on it. He then pointed out that the way we naturally tried to balance was to force the board down in reaction to movements. He taught us to instead balance our bodies, and if we were truly balanced, the board would be too when we stood on it.
The teacher I like best (who's in the San Diego area) told me that her dream was to get more athletes to realize how much they could get out of it.
If you give it a try, I'd be curious to hear your assessment. The Alexander work is one of very few practices I use every day -- "use" isn't the right word; it's integrated into my habits -- and I have reaped rich rewards from it. To pick a simple example, I've gone on many long motorcycle trips over the years. Typically once I'd been riding for a day or two pain management would become an integral part of the trip. The last trip I did I was astonished at not having that problem any more; I'm pretty sure the AT stuff was the reason.

A huge point of change for me was due to this post: http://news.ycombinator.com/item?id=1269951. To sum it up, tension - and the resulting psychogenic pain - was the major, possibly the sole cause for my pain. Not posture, not lack of exercise or some defect in the spine. At least, since just reading part of this book and all of its predecessor, my pain has gone from constant/unmanagable to a minor annoyance. There is some real empirical evidence behind Sarno's research.
A good book I've read on the Alexander Technique is How You Stand, How You Move, How You Live by Missy Vineyard. http://www.amazon.com/How-You-Stand-Move-Live/dp/1600940064
Somebody would give a shot at explaining why (most) Brazilians were singled-out in this example?
Most people who don't live in a sedentary society probably still have good posture and maintain their natural skeletal alignment. I don't know if this applies to all of Brazil.

What I've noticed from years of "sitting jobs", is that you need to keep the hips, lower back firing/moving. Exercise balls helps a lot. I love siting on exercise balls, as they keep the hips, lower back engage. While sitting on my ball and working, I can rotate my hips in any direction, keeping my muscles stretched/firing. Even those "sitting discs" work well: http://www.amazon.com/FitBALL-Seating-Disc-12-Green/dp/B0011...
