Final answer:
Medicare is the healthcare system primarily for people over 65, which is a key part of the safety net for older Americans, providing health insurance coverage in retirement. A significant percentage of workers anticipate working past retirement age, which can impact their health insurance options, including Medicare.
Step-by-step explanation:
The public healthcare system that offers insurance primarily to people over sixty-five years old is Medicare. Medicare is designed to provide health insurance coverage for older individuals, ensuring that they receive the medical care they need after retirement. This program is separate from Social Security, which provides retirement income, although both are entitlement programs that most American workers will qualify for through their work history. It's important to note that Mark can still be covered by his employer's Group Health Plan even after reaching the age of 65. Legislation has evolved to offer greater protection and benefits to those who are nearing or at retirement age, with Medicare as a cornerstone for healthcare coverage for seniors.
A poll from May 23, 2013, indicated that 76 percent of U.S. workers believe they will continue working past the traditional retirement age, reflecting the changing landscape of retirement planning and the need for continued healthcare coverage through programs like Medicare.
