Dot com bubble. Real estate bubble. Commodities bubble. Healthcare bubble? How can the US healthcare system be a bubble when tens of millions are uninsured and more people fall through the cracks daily? The media, public, and politicians alike have been more concerned with the inadequacies of the system than with its rapid growth. US healthcare spending has grown enormously, exceeding the rate of inflation for decades to become the largest sector of the US economy. The United States now spends over 16% of its GDP on healthcare, almost double the average for developed nations.
Perhaps Americans just demand the best and priciest healthcare, with the most modern technology and treatments. Other insurance prices are on a steep rise, including home, accidental and auto insurance. If Americans paid for healthcare themselves, this would simply represent a rational spending choice. But the federal government now incurs 60% of all healthcare spending, meaning that taxpayers, and not individuals, pay for most of our healthcare. Medicare, Medicaid, and other direct government healthcare accounts for 46% of healthcare spending, while tax breaks on healthcare subsidize another 10-15% of healthcare spending .
At current growth rates, government healthcare spending will exceed the entire Federal budget by 2050 . Total spending on healthcare will near one-third of GDP by 2030. It’s unlikely that the US can devote 1/3rd of all productive capacity to healthcare without crippling other sectors of the economy and reducing overall economic growth. The healthcare bubble thus dwarfs all previous bubbles in size, since the technology, real estate, and energy sectors are all so much smaller.
How will the bubble pop, and what will its effects be? Since most healthcare spending is federal, the bubble will pop when the government can no longer afford its healthcare outlays. The US has been able to borrow freely by issuing debt for many decades, but this will eventually end once our debt exceeds GDP. With the current downturn, government debt may actually exceed GDP by 2015 . Thus the reckoning may come sooner than many expect.
Will healthcare reform contain costs and deflate the bubble gradually? Most reform plans focus more on increased coverage than on cost control, so they may exacerbate the problem. Eventually the hard choices will have to be made, and they will include some combination of reducing Medicare benefits, cutting provider reimbursements, openly rationing government health care, and limiting the tax break on health insurance. I just hope that some of the hard choices are made before we are collectively up against a fiscal wall.
 $200 Billion in taxes are foregone as a result of the employer-based healthcare tax deduction, equivalent to 10% of all healthcare spending. When this subsidy is included the government’s share of healthcare spending rises to 56%. This analysis does not include the exemptions on property taxes and sales taxes that healthcare providers receive; adding these subsidies in would likely drive the government’s share of health care spending over 60%.
 The CBO predicts that Medicare and Medicaid will account for 14% of GDP by 2050. This figure doesn’t include healthcare spending through the VA system, SCHIP program, and other federal healthcare programs, which total $100 Billion in spending today. If these programs also grow commensurately, total government spending may near 18% of GDP in 2050, roughly equivalent to total government revenue.
 This projection of public debt growth shows that US government debt will exceed gdp by 2050. This only takes into account debt held by the public, however. Gross government debt is already above 65% of GDP, and may grow to 75% by the end of 2010 as a result of the recession and stimulus spending. With deficits of $500B+ per year possible for several year, US total government debt could exceed gdp in less than 10 years.
