The broken window fallacy is an incomplete parable to compare early 20th century markets to. The shop keeper would have to own 70% of all the business in the town, taking all profits for himself paying his employees as much as he sees fit, with largely only his own businesses for them to purchase items from keeping them indentured more or less. The shop keeper was also able to use persuasion to prevent new business ventures from developing, ensuring his own oligarchy.
