This Wall Street Journal piece on the reality of costs for public health care programs is a keeper. It will make you cringe. If it doesn’t, it should.

Thanks in part to expansions promoted by California’s Henry Waxman, a principal author of the current House bill, Medicaid now costs 37 times more than it did when it was launched—after adjusting for inflation. Its current cost is $251 billion, up 24.7% or $50 billion in fiscal 2009 alone, and that’s before the health-care bill covers millions of new beneficiaries.

Medicare has a similar record. In 1965, Congressional budgeters said that it would cost $12 billion in 1990. Its actual cost that year was $90 billion. Whoops. The hospitalization program alone was supposed to cost $9 billion but wound up costing $67 billion. These aren’t small forecasting errors. The rate of increase in Medicare spending has outpaced overall inflation in nearly every year (up 9.8% in 2009), so a program that began at $4 billion now costs $428 billion.

Clearly, any health care reform must infuse competition — real competition — into the marketplace. JLF’s Joe Coletti explains the key elements of consumer-driven health care reform in this interview.
