Funny that some startups by middle class people thought "hustle," meant energetic teamwork like on a kids sports team, whereas if you had any street smarts at all, hustle means getting leverage over someone by pre-empting their ability to reason accurately, often by bullying, nagging, feigning offence, and exploiting their agreeableness by making them think they "owe," you.
Preying on human goodness like reciprocity, empathy, fairness, and agreeableness is basically what a hustler and hustle tech does.
... Something relevant to street culture rather than middle-class culture?
