There are three major assumptions in your question, that there is a true "nature of reality," that there are people who see it better than others (with you being one of them) and that it is useful to be able to see the nature of reality.

None of the three assumptions is even remotely true if you are talking about sufficiently deep levels of understanding reality. For the purpose of argument, let's make up three arbitrary levels of depth for reality:

1. Ordinary reality: the true nature of our world, how sex, money and power work, whether the world is fair or not, how to get ahead pragmatically, whether our current lifestyle is sustainable or not, how to help the poor.
2. Fundamental reality: the stuff of physics, mathematics, logic, philosophy that is not metaphysics, ethics, the nature of evil, suffering and pain etc.
3. Metaphysical reality: the nature of space, time, consciousness and other things that we think exist, but are beyond the reach of falsifiable science or analytical arguments (beyond a point). The axiomatic foundations of Level 2.

Your question only makes sense at Level 1. Here, within limits, the first two assumptions are true. For example at this level of "reality" corporations do control more of our lives than most people realize, there ARE people who realize this more clearly than others.

Is it actually useful to realize this?

Decidedly not. At least not for individuals. Being able to see reality more clearly than others is an accidental human trait (as Liron Shapira points out). Wanting to do so is a very perverse desire. Most people want sex, money, power, friendship and community at Level 1. These are normal desires. A minority of people want to see reality as clearly as they can. A very perverse desire.

Up to a point, being able to see reality clearly helps in the pursuit of less perverse desires like sex/money/power/friendship/community. Beyond that, it is a liability.

Wanting to see reality clearly for its own sake gets you to completely useless levels of precision that come at the cost of the ability to pursue other goals.

1. Optimism is very good for making money. Beyond a point, seeing reality too clearly is depressing and makes you pessimistic and therefore less capable of making money.
2. Confidence is very good for getting sex. Beyond a point, seeing reality too clearly makes you far less confident about what you know, and therefore far less confident about yourself.
3. A blindness to others' pain is very good for getting power. Seeing reality too clearly makes you very sensitive to others' pain. Again bad if you want power.
4. A blindness to the ulterior motives and deeper psychology of interpersonal relationships makes you able to enjoy friendship in normal ways. Removing that blindness makes friendship harder.
5. Lack of awareness of things like social proof and groupthink helps you join and enjoy community life. Add that awareness at a sufficiently acute level, and it will poison your ability to enjoy community life.

In summary, if you think you can see Level 1 realities more clearly than others, be careful. You have a curse. If you are lucky, you could just be deluded.

Most people never think about Level 2 or Level 3 reality very seriously, if at all. If, among those who do, you think you see things more clearly, chances are very high that you are wrong.
