Expand Medicare to include all Americans
Instead of re-inventing the wheel, Congress should expand Medicare to include healthy young adults ages 18 to 29 (18 to 29 is an arbitrary numbered group to start).
The best part of this idea is taken from the Obamacare playbook. Young healthy adults contribute to the funding of Medicare and are not as great a health burden as older adults.
As the 18 to 29-year-olds age, the Medicare age bracket advances to accommodate the aging population.
Example: You become eligible for Medicare while in your pre-30-years. And you stay eligible for Medicare as you age.
This plan would squeeze out the in-efficient and expensive patchwork insurance plans currently in existence.
What about existing 30 to 64-year-olds? Most mature adults already have healthcare and would continue on their plan until reaching age 65.
In essence, this is a self-growing Single Payer Healthcare plan. Best of all, it already exists.
