Obamacare Struggles to Sign Up the ‘Young and Invincible’

Amid intense efforts by the Obama administration to target the uninsured in the U.S. president’s final months in the White House, sign-ups for health plans created under his signature domestic law are expected to rise by about 1 million next year.

But the Obamacare exchanges are still not attracting enough young, healthy and higher-income individuals who could help spread the health-care costs of the sickest over a bigger group.
