Final answer:
Young adults are experiencing a delay in reaching adulthood milestones such as financial independence and leaving the parental home due to economic and cultural changes, leading to phenomena like the Boomerang Generation.
Step-by-step explanation:
A negative outcome for young adulthood is the delayed achievement of traditional milestones of adulthood, which includes completing school, leaving home, becoming financially independent, marrying, and having a child. Current cultural and economic shifts, identified by researchers such as Henig and Arnett, are leading young adults to postpone these milestones.
They face challenges such as underemployment or the need for additional education, which in some cases lead to the Boomerang Generation phenomenon, where young adults return to live at their parental home due to financial struggles. Alongside these economic factors, the social networking consequences that impact college applications and job opportunities add to the complexity of the negative outcomes faced by Millennials in their transition to adulthood.
