Charles Blahous is the J. Fish and Lillian F. Smith Chair and Senior Research Strategist at the Mercatus Center at George Mason University, where he specializes in domestic economic policy and retirement security, as well as federal fiscal policy, entitlements, and health care programs. Blahous is the author of the influential studies The Costs of a National Single-Payer Healthcare System and The Fiscal Consequences of the Affordable Care Act. Medicare for All is expensive -- and Dr. Blahous tells us exactly *how* expensive this single-payer system would be. This would impact not just the very top of the 1%, but your everyday middle class family.
