"questioning what's been happening and what the reasons could be" - and that's the issue, in a nutshell. Looking for reasons. It's a very human thing, to look for reasons. It's also a very human thing to credit the wrong thing as being the 'reasons''. That's the very foundation of religions.
We like there to be reasons because it's 'safer' than things happening for no reason at all. The concept of chaos is quite scary.
We don't like the real reason to be something totally outside human control, because that's as scary as chaos, because nothing can humanly be done to bring it back under 'control'.
We reach for a reason that is attributable to human action, and we like these reasons to be simple to understand. Even if the problem is complex, we want a simple solution - a sacking, a new law, a prosecution, a payrise - a conspiracy.
And consider those pictures made up of dots, where if you're up close all you see is dots, and if you stand well back you can see a picture. It is still just dots, but our brain fills in the blanks and makes the picture. We see the many dots of shit happening right now and our brain fills in the blanks to make a conspiracy.
Truth is, there's a lot of chaos and complexity out there. A perfect storm of it, in fact. And that is what we are facing; a perfect storm of chickens coming home to roost, and greedy opportunists taking advantage of chaos, and unintended consequences. And that is very, very scary. So scary that some people would genuinely prefer to look at the picture and see conspiracy because then it's 'someone's' fault, and those 'someones' can be made to back off and put it right again. A simple solution to a complex problem.
It's also worth bearing in mind the nature of conspiracy. It needs to involve groups of people working together. How many people would this conspiracy require? Far to many for it to be plausible. There's even been research on this! (journals.plos.org/plosone/article?id=10.1371/journal.pone.0147905).
