Unless you go out and talk to them directly (and a whole lot of them at that), then all the things the mob "says" will be whatever your source of media tells you they said (that's hearsay in a court of law).
Easier said than done. None of the movements is close by for me. The best I can do is read what they write on the net -- and that falls largely into either politically... optimized, to put it mildly, statements by the "official" sites, or quite random comments by random people.
I really spent a lot of time trying to get a broader picture of what is wrong with politics. Not just now, but for many years; anybody surprised at what happened the last years was living with his head in the sand. The conclusions I came to just don't address the problem even remotely the way politicians and activists intend to address it now. I feel like being in a lost, tiny party that just isn't compatible with the rest.
Right now, Bitcoin is the only movement where I feel at home. The difference lies in not just randomly having a good point (normal case), but instead making some mistakes while wanting the right thing (Bitcoin case).
So, admittedly, part of my reaction to the protests' statements come from my personal frustration on the topic. I want to scream at these people, "What the hell are you doing?" The answers are visible openly, why don't they see any of them?
Also, your criticism of the "they" language is quite on sided. It happens to be the best way express the thing when you see something being done but can't see exactly who is doing it. The things they list might even be unintended byproducts of actions where a distinct group of "they" cannot even be named or is too big to be named and lumped under a single group. Also, yes, I expect the purpose behind these sentences to be exactly to get more people involved. This is not a group of people who are demanding change. This is a group of people who've decided to make change happen. That includes figuring it out.
They're not simply just shouting their grievances in anger. That would be just a demonstration. They're actually talking out there. Learning things, discussing things. What they will achieve remains to be seen, of course. However, it's a lot of people who have decided to actually do something. They don't yet know what it is. They're still figuring out what's causing the things they want to fix. It shows that people are waking up to the fact that they can fix things, they don't need to just sit and wait for "someone else" to do it. People are regaining their own initiative.
All you said is true. This is how they see it, it's what they do and intend, and their intentions are likely good.
Unfortunately, it doesn't contradict my statements. They are
failing at figuring it out. There's more noise, but the amount of truth and good concepts behind it has not increased.
Macroeconomics is a hard combination of logic, statistics, empirical knowledge and game theory. You can't faze that with some mass movement any more than you can destroy a river by throwing stones into it. Unless you know exactly where to throw them, it will just form a new, similar path.
I'd really love to explain to people what to do, but I can't find any way to prove my opinion better than that of others, at least not without using arguments that are so excessive, someone understanding them would know what to do anyways. This is the great dilemma I just can't solve, and the reason I sit here trading Bitcoins instead of changing the world.
