America’s Social Mobility Problem: What Went Wrong—And How AI Could Make It Worse (Or Better!)
For generations, the American Dream was built on one powerful idea: each generation would do better than the last. Historically, this wasn’t just rhetoric—it was reality.
From 1850 to 1950, the U.S. experienced a massive rise in social mobility, fueled by the expansion of public education. A new study shows that as schooling became universal, a child’s success became less dependent on parental background, giving more people a shot at economic advancement. But if mass education was such a game changer, why has mobility stalled in recent decades?
More importantly, as AI reshapes the job market, will it expand opportunity—or lock it in place?
What We Got Right: The Rise of Education-Led Mobility (1850–1950)
A recent paper by Lukas Althoff, Harriet Brookes Gray, and Hugo Reichardt finds that universal education was the single biggest driver of mobility in U.S. history. Before mass schooling, a child’s economic prospects depended heavily on their parents’ education—especially their mother’s. But as public schools expanded, the reliance on parental human capital weakened, allowing more children to move up the economic ladder.
This shift transformed America into a true land of opportunity. The logic was simple: if education is broadly accessible, it creates a fairer playing field.
But that engine of opportunity is no longer working the same way.
Where We Went Wrong: The Decline of Mobility (1950–Today)
Raj Chetty and colleagues have shown that economic mobility in the U.S. has sharply declined over the past several decades. In 1940, 90% of children earned more than their parents. By the 1980s, that number had fallen to 50% (Chetty et al., 2017).
So what changed?
📌 Education Quality Became Unequal – While mass schooling once lifted all boats, today’s education system is deeply divided. Wealthy communities have well-funded schools, advanced coursework, and pathways to elite colleges. Meanwhile, lower-income communities struggle with underfunded schools, fewer resources, and limited opportunities.
📌 Rising Economic Inequality – The gap between rich and poor has widened, making it harder for low- and middle-income families to move up. Housing, healthcare, and education costs have skyrocketed, making the path to economic security much steeper.
📌 The Job Market Shifted – Many well-paying, middle-class jobs have disappeared. A college degree used to guarantee a stable career, but income inequality within educational groups has widened, making upward mobility far less certain.
AI Disruption: The Next Big Test for Mobility
Now, we stand at another crossroads. AI is transforming the workforce—but will it expand opportunity or reinforce inequality?
For many jobs, AI will automate technical tasks, shifting the value of human labor. This means that the most important skills in the AI era won’t be technical AI skills—but the human skills AI can’t replace:
✅ Critical thinking & problem-solving – The ability to interpret complex situations, challenge assumptions, and make ethical decisions.
✅ Social perceptiveness & adaptability – Understanding human emotions, leading teams, and adjusting to dynamic environments.
✅ Creativity & interdisciplinary thinking – AI can analyze data, but humans excel at making connections between fields and thinking outside the box.
Ironically, the skills most essential for the future are often developed through the humanities, social sciences, and interdisciplinary education—areas that are often overlooked in workforce discussions.
What Needs to Happen Next?
Just as universal schooling fueled economic mobility in the past, we need to think about how to ensure opportunity in an AI-driven future. That means:
📌 Prioritizing Education That Strengthens Human Skills – If AI can handle routine tasks, the education system must shift toward problem-solving, creativity, and emotional intelligence—not just coding.
📌 Investing in Workforce Adaptability – Workers need lifelong learning pathways to transition into new careers as industries evolve.
📌 Ensuring AI Doesn’t Concentrate Wealth at the Top – Without the right policies, AI risks exacerbating inequality rather than reducing it.
The Big Question: Will AI Be a Force for Mobility—Or a Barrier?
The story of 1850–1950 teaches us that broad access to education was the key to unlocking opportunity. But it also warns us: when education and economic systems become unequal, mobility suffers.
As we look to the future, ensuring AI expands opportunity—rather than reinforcing existing divides—will be one of the biggest policy challenges of our time.
