I've even seen comments on here regarding immigration that simply said if someone has ever been arrested then they shouldn't be allowed into the USA. (No qualifying statements on recency or severity, or even acquittal.)
With regards to crime (including the mere accusation of sexual things) the sentiment of the USA runs counter to the aspiration and promise of social mobility of the USA.
Yes others profit from maintaining the status quo, but worse is that people are judged for life, based on a single incident in their past. And as the article points out, the zero tolerance amplifies the destructive nature of a society that judges.
