Error or not?

Shouldn't it have been "self-perpetuating bottleneck which purports to narrow bottlenecks will suffer from the same contradiction" instead of "self-perpetuating bottleneck which purports to widen bottlenecks will suffer from the same contradiction"?

...
Marx glimpsed this analysis — it's the fundamental contradiction of Capitalism — but he failed to nail it. There's nothing particularly magical about capital as a bottleneck: any self-perpetuating bottleneck will have the same effect, and any self-perpetuating bottleneck which purports to widen bottlenecks will suffer from the same contradiction.

As an exercise for the reader, look for self-perpetuating bottlenecks in history and modern societies. They're all over the place. For example, the self-perpetuating bottleneck of feudalism is ownership of land.
