Starr gives a thorough history of not only health care reform but general market-trends in United States health care, beginning around the early 1900s until 2013. Of course, the book is out of date, but all books on reform eventually will be.
I originally read the book to learn more about health care, as I am losing my insurance this year. Not only does he cover nearly a dozen terms ("managed care," "HMO," "PPO," "fee-for-service," etc.), but he highlights how the employer-insurance system operates and how it is subsidized.
The book also tells a surprisingly honest story of the corruption within health care reform coming from both parties in response to the pharmaceutical industry, hospitals, doctors, and of course the private insurance lobbies. The book could be best summarized with a few pillars: the US diverged early on from European countries and failed to implement single-payer, no president until Bill Clinton seriously pushed for massive reform, interest groups (including unions) often opposed reform efforts or accepted minimal reform as a compromise to public pressure, people already covered by government insurance were unwilling to risk or support any changes, and Obama pandered to a right-wing that was unwilling to negotiate in Congress or in the courts.
The book is also surprisingly skeptical of Obamacare, and this has aged well. The author does not specifically endorse any particular policy, acknowledging they all have tradeoffs, including single-payer's lack of political capital at the time. It would be fascinating to see if his analysis has changed since. Highly recommend for someone interested in political theory (policy traps, economic incentives, capitalism vs. socialism, etc.) as well as someone who wants to learn more about the convoluted US health care system without reading a bunch of legalese.
