Thus, health-care reform should be based on policies that diminish the health-care wedge rather than increase it. Mr. Obama’s reform principles—a public health-insurance option, mandated minimum coverage, mandated coverage of pre-existing conditions, and required purchase of health insurance—only increase the size of the wedge and thus health-care costs.

According to research I performed for the Texas Public Policy Foundation, a $1 trillion increase in federal government health subsidies will accelerate health-care inflation, lead to continued growth in health-care expenditures, and diminish our economic growth even further. Despite these costs, some 30 million people will remain uninsured.

Implementing Mr. Obama’s reforms would literally be worse than doing nothing.
