Your "question" reads more like a rant, but on the off chance you are really asking, I'll try to answer or at least comment.
But badly formulated and/or unclear problems get considerably less attention
Of course. In fact, you'll probably notice that most of them are accumulating close votes or have already been closed. That's how we handle bad questions on SE. One point of closing is so that the questions gets no attention at all.
This is deliberate. We don't want people coming here, posting crap, and then getting the desired result. If they do, they'll just be back doing the same thing again. Also, others will see that it works, and they'll be doing it too.
Unfortunately, there will always be a few misguided do-gooders that want to help the poor OP, or can't resist answering something simple to look smart or rack up a few quick rep points. Because of these people, we have to close questions. That prevents everyone from answering.
I've been trying to "help" a few OPs with their problems
Don't do that. Keep the bigger picture in mind. At first glance it may sound good to help any one person. However, in the bigger scheme of things it actually damages the site to help those that dumped crap on us. See above.
If you really want to help, vote to close the question as unclear. Also downvote if you think it is badly written. Then you can ask the OP for clarification in a comment or suggest ways to improve the question. If the question is improved before 5 close votes accumulate, then OK. Otherwise, the close process will proceed without delay.
It is important that the OP make any changes to a bad question. That way he doesn't get away with dumping crap and getting the desired result. Only if he has to go thru the trouble of fixing the mess himself does the cost/benefit tradeoff change to posting better questions in the first place.
Note that most of the time, there is no response to such comments. Waiting to close in that case just leaves the noise on the site longer.
Yet OPs leave out crucial stuff
Well, duh! Is this your first experience on the internet or something? Of course they do.
Those of us who haven't just emerged from living in a cave know that there are plenty of stupid and lazy people in this world. Some of them inevitably visit here. We can't fix that. What we can fix is how we respond to them. By insisting on a minimum quality level for question before help is given, the morons, ingrates, and sloths are discouraged.
Now some OPs are probably kids pretending to be non-kids (no joke), others are probably just clueless when it comes to communication
Probably true, although irrelevant. Bad questions are bad questions regardless of the reason, and must be expediently dispensed with as such.
But I have a suspicion growing, I believe some OPs are working on "inventions" they're trying to keep secret.
Maybe, but again, that's irrelevant.
