Public Health at a Crossroads: Equity, Trust and the Future of American Health

I have spent years thinking about healthcare not simply as an industry, but as an ecosystem.
And I am worried about that ecosystem.
We are living through a period of extraordinary change: recurring food, drug and medical-product recalls; declining confidence in vaccines; environmental changes affecting the air we breathe, the water we depend upon and the communities in which we live; rising healthcare costs; and growing distrust of the institutions responsible for protecting public health.
At the same time, our national debt is approaching $40 trillion.
Eventually, fiscal pressure becomes a public health conversation too. When governments face difficult choices about spending, the programs serving vulnerable communities can become increasingly difficult to protect. Yet the need has not disappeared.
CDC data show that kindergarten MMR vaccination coverage declined from 95.2% in 2019–2020 to 92.5% in 2024–2025, while vaccine exemptions continued to rise.
That is not merely a vaccination statistic. It is a warning about trust.
And trust may be one of the most important social determinants of health we rarely discuss.
I live and work in the South, where I have witnessed how geography, race, poverty, transportation, healthcare infrastructure and politics can intersect. A person's ZIP code can still influence whether there is a hospital nearby, whether specialists are accessible, whether transportation exists and whether affordable coverage translates into actual care.
We talk frequently about the Social Determinants of Health (SDOH): Housing. Food. Transportation. Education. Employment. Healthcare access. Environment.
But I believe we must ask a harder question:
How do we address the social determinants of health while simultaneously losing health equity?
Health equity does not mean everyone receives the same thing. It means people have a fair opportunity to achieve their highest level of health—and that requires acknowledging that some communities begin with barriers others do not face.
For many Americans, simply saying “use the Marketplace” does not solve the problem. A plan can exist and still be unaffordable. Coverage can exist while transportation does not. A prescription can be written while the patient cannot afford the medication. A specialist can accept the insurance while being located 100 miles away.
That is the difference between healthcare availability and healthcare accessibility.
Meanwhile, our political discourse is becoming so consuming that I fear we are becoming desensitized to the human consequences of policy. Public health has become red versus blue.
Cancer does not ask how you voted. Diabetes does not check party registration.
A hurricane does not distinguish between conservatives and liberals. And infectious disease does not respect county, state or ideological boundaries.
Our personal biases cannot become barriers to protecting one another.
If we are serious about SDOH, then our next generation of public health policy must reconnect health equity, health literacy, environmental health, affordability, prevention and community trust.
We need trusted messengers inside communities.
We need healthcare information people can understand.
We need policy developed with communities rather than merely for them.
We need to protect prevention while addressing affordability.
And we must be willing to measure policy not only by what it costs but by who is helped, who is harmed and who is left behind. Because the greatest threat to our public health ecosystem may not be one disease, one policy or one political administration. It may be our growing willingness to accept inequity as normal. I refuse to accept that as normal.
Health equity must remain part of the American public health promise.
The question before us is whether we still have the collective will to protect it.
