To hope for the best is not a sin
(although it’s not much of a strategy, either)
Let us start with a bit of "folk physics", based on just about everyone's lived experience: It is easier (and usually cheaper/faster) to BREAK something complex than it was to BUILD it. Throw a rock at a TV screen, drop a lit match in a house... We all know.
Economic actors that learn to profit from the sequelae of "breaking stuff" and then occasionally to CAUSE stuff to be broken (optimizing their profitability with foreknowledge of event timing) would be expected to have an inherent advantage over those limited to chasing the market and only capable of responding a news cycle later.
Given the time, expertise, knowledge base and computational power commanded by the most powerful financial/investment/banking interests in the world and their attention to even a few .001% of advantage in their constant struggle to maximize profits and acquire more "stuff" (and their promotion of those managers exhibiting best quarterly gains!), combined with the dilution of personal ethical & moral responsibility for collateral damages which a large organization grants? A person (thinking there would be no PERSONAL blowback!) who figured out how to most economically make those extra .001% here and there (yo, shorting stocks?!) could go far by throwing a monkey wrench in a gear box (critical canal "accidentally" blocked for a month supply chain ripples lasting far longer?) or dropping a match (ethnic tensions fanned into open warfare by a respected leader's assassination?).
After the first investment fund manager "went there" and their competitors noticed, they all MUST join in to keep up, assuring that those organizations capable of so profiting would "never let (the opportunity to precipitate) a good crisis go to waste".

This is all just one of the premises for a dystopian science fiction novel I'm story boarding, of course. The real world can't work like this, there would be constantly escalating financial and social chaos, the winners in profit margins conducting buyouts and mergers of investment houses, reducing their ranks to only a few gigantic multinational investment funds. Then, perhaps, only one gigantic financial holding company remaining & effectively ruling the world.
