Don't disagree with the facts but the suffering of humans depends as much on the content of their thoughts as it does on material conditions. A civilisation at the apparent height of its power and security can eat itself from the inside and decline rapidly. A wealthy individual living a privileged life can be beset by anxiety, and so on. Both of these things are strongly affected by the ideas that predominate in a given era. These include subtle ideas which can't readily be identified and which nevertheless spread and cause harm. So those ideas are a relevant part of the environment when considering which was the worst year so far.
