There are two groups of people: blamers and doers. For example, people will often blame local government for issues such as not disposing of fly tipping garbage quick enough, but they will not do much to clean up the pavements with sofas or fridges around their house – a man with a van can often drive over these large bits of garbage to a recycling centre for like $30/£30 an hour. Sometimes people will say government is spending money poorly, but they will not have participated in any of the consultations the government did on the matter, even if they were online or accepted mail-in comments. And in workplaces, they will often blame other departments without having put in elementary effort to resolve the issues with them. Sometimes people will blame government services for collapsing – there are certainly many YouTubers that constantly moan about how bad public transit is in many regions of the US, but few will donate to groups and politicians that genuinely want to replan public transit. Few will campaign for them, which can be done online in the fraction of a time it takes to produce a video.
If an org gets taken over by the blamer culture, it is doomed. These people will make no attempt at fixing problems, even when that would sometimes take 5 minutes and an email, but they will moan. And they will blame, and sometimes they'll blame the person suggesting an easy and workable course of action to resolve the problems.
Interestingly, sometimes resolving the problem takes less effort than sustained moaning, and certainly less mental strain. And still, people who tend towards the blamer group will blame and moan. Though I make no insinuation that moaning doesn't have any other benefits (such as YouTube video revenue, virtue signalling, and similar) – it is clearly appealing to one of the two groups I mentioned.
