The orphan-crushing machine is luckily just a metaphor for the way media tends present the stories in which a person remedies the effects of sociopolitical injustice as "heartwarming" without questioning why said injustice exists in the first place. The metaphor satirizes these stories by comparing them to a person raising money to keep 200 orphans from getting crushed while nobody questions why an orphan-crushing machine exists and runs in the first place.
The orphan-crushing machine can also be interpreted as a metaphor for late-stage capitalism, where useless products and infrastructure can be produced with the single purpose of further inflating business numbers and creating jobs.
