I recently spent 40+ hours over 4 months getting my wife enrolled in Medicare. The craziness of how challenging this was for someone with, arguably, a lot more specialized knowledge of the healthcare system than the average person (and even I needed to invoke the help of my Congressperson’s staff to get across the finish line) could itself be the topic for a column. There are many reasons for this situation, but one I want to explore is the role of the market. Although Medicare is ostensibly a government program, much of it is privatized. Consumerism has been proposed as the answer to the American healthcare woes of high costs with lagging results in terms of actual health outcomes. Give people more choices, with transparency about costs and quality, and the invisible hand of the market will make it all better. I have long been suspicious that this can actually work with healthcare (it certainly hasn’t so far). But now I find myself wondering whether even if it could deliver better value, is it the right thing to do?
To someone like me who went into healthcare out of a sense of mission and calling, consumerism has always felt a little icky, though I couldn’t well articulate why. I recently read Michael Sandel’s 2012 book What Money Can’t Buy: The Moral Limits of Markets. In it Sandel, a Harvard political philosopher who has also written on justice and “meritocracy,” talks about the enormous expansion in recent decades, particularly in the US, of the role of markets in society. He describes the shift from a market economy, which is a tool for efficiently organizing productive activity, to a market society where market values dictate nearly every aspect of human activity, not just economic transactions but social relations. As the title of the book suggests, he believes that some things should not be left to the market, not for practical reasons but for moral ones. He raises two overall causes for concern: equity and corruption. While the book is not primarily about healthcare, I couldn’t help but conclude that it is one of the things where more marketization should raise alarm bells. I’ll tackle the latter concern, corruption, in the next installment of this blog. For now, let’s consider how marketizing healthcare threatens equity.
The basic principle behind market transactions is that people, acting in their self-interest, pursue those goods they most want. Prices are determined by the balance of supply and demand, and goods are then allocated to the people who most value them based on their willingness to pay. If tickets to the Vikings and a dinner at the Four Seasons each cost $300, then the person who prefers football to fine dining will get the tickets because they are willing to pay for them, leaving the dinner reservation to the gourmand who really wants them. Each one, pursuing their own interest, gets what they want. Everyone is happy.
This assumes that those individuals have the means to purchase one of these goods. I might really want those Vikings tickets, and be willing to pay $300 for them, but if I don’t have that $300 I can’t have them. Markets are based on allocation according to willingness to pay. But willingness to pay is not the same as ability to pay. Money is unevenly distributed in society – increasingly so in the US – so the ability of the market to allocate goods to those who most value them is restricted. (Indeed, when someone is constrained enough, choices may be not only limited, but coercive. I may not want to sell my plasma, but if I’m desperate enough I will.)
With greatly uneven distribution of economic resources – of ability to pay – some people will be unable to obtain something they value a great deal. “I’d give anything for…” is a common sentiment, but very few people are in a position to literally give anything. At the same time others with excess resources may obtain things they don’t have a great desire (or need) for simply because they can. This may not matter for stereo equipment or luxury cars, but can lead to troubling inequities if we are talking about the distribution of medicines and healthcare services.
Fair markets also assume equal access to information about the transaction. In reality, not only is money distributed unevenly, so is information. As my Medicare enrollment experience illustrated, modern healthcare is incredibly complex. And transparency is at best a tiny step toward equalizing information. There are so many variables, with so many degrees of uncertainty, from so many different sources, it is unrealistic to think that the ability to process it can be equal. (Even if there weren’t active disinformation going on, including from our own government.) If people have different levels of knowledge about the benefits and drawbacks of a good, different abilities to know what they are getting for their money, then the transaction cannot be truly equitable.
If a healthcare market is prone to inequity by allocating the goods and services based on willingness (or more accurately ability) to pay, is there a more equitable alternative? In many systems, willingness to pay is replaced by willingness to wait, or queuing. This is a criticism often raised by market advocates about single-payer, non-market-based systems, that they lead to waits for care. This is often true. But it can be argued that time is distributed more evenly in society than money is, though not completely so, and therefore willingness to wait is a fairer system. And to be clear, we also have waits, though in our system, it’s a bimodal distribution: some people don’t wait very long, while others wait literally forever.
And there are ways to make a market-based healthcare system more equitable. Health insurance does that by spreading risk across the population, and income-based subsidies for insurance can reduce disparities in access. Standardizing benefits and information, like the ACA marketplace or the letter system for supplemental Medicare (“Medigap”) plans, can reduce information disparities, though trust me, it remains complex.
But inequity isn’t the only concern about markets in healthcare. Markets are about allocating value, but are agnostic about values. It is the corrupting effect of markets that is even more troubling. We’ll look at that next time.
