>How can a society recover from a situation where these kind of people hold most of the power?
I won't talk in terms of individual action, but in terms of policy change, most of these elites are bred in universities that receive government funding to stay afloat. When you hear stories about the idiots going hundreds of thousands of dollars into debt, what they're really talking about is going into huge amounts of debt trying to form connections with the elite. Universities should be places you go to learn the foundations of Western Society, to network with other elite, or to gain deeper knowledge/experience to further your career. If they weren't receiving free money from public assistance, that's the only groups that would be attending universities and they would be extremely difficult to subvert. Without the subversion of the university, the overton window could never have shifted in the direction it did. The subversion of the university happened first when congress decided to subsidize veteran's education to keep veterans satiated as welfare whores to prevent an uprising after WWII and later when public assistance started to form after others saw this and wanted in on the pie.
Universities aren't the only problem, I'm just using them as an example here. The real point is this: If you do not put something in the public domain/government domain, there is nothing to try to subvert. Maybe it would be better for governments to focus on the handful of tasks they are philosophically supposed to accomplish rather than try and hold domain over every aspect and facet of someone's life. More importantly, governments are bloated messes that rarely do things efficiently. Stop looking for a means of confronting your enemy and start looking for means of circumventing your enemy or accomplishing your goals independently of your enemy. Paying someone under-the-table or in non-taxable means as "favors to each other" where they get the full fruits of their labor for instance, both circumvents your enemy and creates an arrangement that a lemming doesn't want to see ended by the official government. Conspiracy to commit criminal offenses are the thoughts embraced by a man poor in skills, soul, philosophy, and tact. The reasonable man instead simply goes around his problems entirely and creates a system that embraces his ideology not on a matter of agreement in philosophy but on a matter of practicality/benefits. Most large institutions suffer from dis-economies of scale and are unable to actually compete with smaller competitors who offer a local service.
Instead of bitching about Hollywood, follow The Wired's platform of launching your own collaborative movie efforts.
Instead of bitching about the social media giants, create local social networks that are not tied to them, as these will grow with time if they are beneficial.
Instead of complaining about the police, form local community efforts to keep an eye on crime. If these are popular enough, eventually the community will be large enough to file to disband the police in favor of your private defense force (this is legal in all 50 states, though it is seldom practiced).
If you aren't an innovated, creator, entrepreneur, etc. Offer your skills in a meaningful manner along these lines, and with the right marketing, you'll see people naturally gravitate to your platform.
Most importantly understand that more inventions "failed" because of lack of marketing or marketing at the wrong place at the wrong time than anything else. Vibrators were marketed poorly as a medical device for decades before they were adopted as a recreational tool for masturbation, as a crude example. These are all just examples. You don't need to make a massive plan for some global-spanning product. Zuck didn't make Facebook in a day. He just had the right marketing to college students who wanted their own private clique and a little luck. The founders of Google didn't start out as a multimillion dollar corporation with its hands in a hundred different pockets, it started as a research project because search engines in the 90s sucked ass. You need to supply a specific good/service to solve a problem that the current institutions in place fail to solve or solve poorly or solve expensively and inefficiently, anon. That doesn't have to be legal, it just has to be discreet enough to go unnoticed and make people very angry if/when the government takes it away from them.
