This structure is self-reinforcing and very resilient: few people here and there rejecting faith in rule of law, or authority of the courts, or money, don't make a difference - we write such people off as weirdos and carry on with our days, secure in knowledge our world will continue to work as it worked the day before. But if sufficient amount of people have their faith falter, that's where the trouble starts.
For example, if enough people stop trusting in the justice system to deliver something resembling justice most of the time, you'll see people ignoring courts and laws and taking justice into their own hands[0]. People start lynching and killing each other, others see them getting away with it, which quickly destroys their trust in the system, and now you're at the precipice. If shooting a (person accused of being) thief is fine, if shooting a billionaire is fine, then why uphold a contract? Might as well get your own at gunpoint, etc. At this point everything stops working - banks, healthcare, fire services, stores. Your country collapses. You probably die.
That is why threats to our shared belief system are so dangerous, and need to be dealt with swiftly and aggressively. It's not about elites in power wanting to stay in power (though it's no doubt part of it for them) - it's because should we all start thinking our social structures don't work, and that everyone else thinks this too, and start acting on this expectation, they'll all collapse in an instant.
