A mono-answer is when all problems lead to one overarching issue, i.e., capitalism.
Similar to a monoculture (where one crop is grown to the exclusion of bio-diversity, creating a fragile ecosystem susceptible to blight), the mono-answer’s simplicity is vulnerable to collapse with one argument.
Reality is complex and by artificially simplifying it, we simplify our faculty for understanding and leave ourselves blind (from hyper-myopia.)
Unfortunately, complex thinkers are dangerous and often alienated. Allies do not want you to have more than one answer; they need you to be predictable to pretend stability through consensus.
