Side hustle first meant a scam, not a second job.
The word hustle entered English from Dutch husselen (to shake or toss), originally describing the shaking of coins in a game of chance. By the early twentieth century, American slang had extended it to mean aggressive effort, and then to swindles and petty crimes. A hustler was someone working an angle, not someone working overtime.1
The compound side hustle appeared in African American vernacular English by the 1950s, describing supplementary income earned through informal or off-the-books work.2 The side marked it as secondary to a main job. The hustle carried its older connotation of resourcefulness in difficult circumstances.
The term entered mainstream usage in the 2010s, stripped of its street-level origins and rebranded as entrepreneurship. Media coverage celebrated the side hustle as a path to financial freedom and self-expression. A 2019 Bankrate survey found that 45 percent of American workers reported having a side hustle.3
The rebranding concealed an economic reality. Research by the Federal Reserve Bank of Minneapolis found that the growth of secondary employment correlated more strongly with wage stagnation and rising costs of housing, healthcare, and education than with any increase in entrepreneurial aspiration.4 For many workers, the side hustle was not a choice but a necessity renamed as ambition.
The older meaning of hustle, a resourceful response to scarcity, may have been more honest than the newer one. A word that once acknowledged economic precarity now disguises it as personal brand development.5
