The idea sounds appealing in its simplicity — one program, everyone covered, no more insurance hassle. But the details reveal why it's far more problematic than the slogan suggests.

The Mercatus Center at George Mason University, using Senator Bernie Sanders's own bill, estimated Medicare for All would cost approximately $32.6 trillion in additional federal spending over 10 years. Even doubling all federal individual and corporate income taxes wouldn't cover it. The Urban Institute, a center-left think tank, put the cost even higher at $34 trillion.

Current Medicare is already in financial trouble. The Medicare Trustees Report projects the Hospital Insurance trust fund will be insolvent by 2031. Medicare pays hospitals and doctors significantly less than private insurance — about 87 cents on the dollar. Hospitals make up the difference by charging private insurers more. If everyone is on Medicare rates, many hospitals — especially rural ones — would face closure. A study in Health Affairs found that about 60% of hospitals would operate at a loss under Medicare-for-All payment rates.

Current Medicare also isn't actually comprehensive — it doesn't cover dental, vision, or long-term care without supplemental insurance. Most seniors buy Medigap plans or Medicare Advantage plans to fill the gaps. The 'Medicare' in Medicare for All would actually be an entirely new program far more generous than what seniors currently have.

Eliminating private insurance would also eliminate choice. About 180 million Americans get insurance through their employers, and surveys consistently show that most are satisfied with their coverage. Medicare for All would outlaw these plans.

Better approach: let people buy into Medicare if they want, expand Health Savings Accounts, increase insurance competition across state lines, and implement price transparency. Give people options rather than a one-size-fits-all government monopoly.
