From the Pew Research Center:
When Americans peer 30 years into the future, they see a country in decline economically, politically and on the world stage. While a narrow majority of the public (56%) say they are at least somewhat optimistic about America's future, hope gives way to doubt when the focus turns to specific issues.
A new Pew Research Center survey focused on what Americans think the United States will be like in 2050 finds that majorities of Americans foresee a country with a burgeoning national debt, a wider gap between the rich and the poor and a workforce threatened by automation.
Majorities predict that the economy will be weaker, health care will be less affordable, the condition of the environment will be worse and older Americans will have a harder time making ends meet than they do now. Also predicted: a terrorist attack as bad as or worse than 9/11 sometime over the next 30 years.
These grim predictions mirror, in part, the public's sour mood about the current state of the country. The share of Americans who are dissatisfied with the way things are going in the country – seven-in-ten in January of 2019 – is higher now than at any time in the past year.
The view of the U.S. in 2050 that the public sees in its crystal ball includes major changes in the country's political leadership. Nearly nine-in-ten predict that a woman will be elected president, and roughly two-thirds (65%) say the same about a Hispanic person. And, on a decidedly optimistic note, more than half expect a cure for Alzheimer's disease by 2050.
