A thousand years ago, humans believed that natural disasters could be predicted by augurs, portents, etc. not out of a rational understanding, but out of an innate sense that "it can't possibly be random". It's reverse reasoning at its core.
Today, the same instincts are alive and kicking, but the current fad is to blame the ultra rich instead.
There isn't some vast conspiracy. But generally it takes a certain kind of person to crave that type of wealth and power. So they tend to all pull in the same direction to keep and build upon said wealth/power. Thus can be viewed as collectively working towards the same nefarious state of things.
And the unpredictability actually has a name and it is "flooding the zone".
