I think you could make a clean argument it's a 1a / 1b sort of problem. Housing & healthcare are two of the most basic needs in a modern society, and both have systemic issues across much of the country.
In NYC, saving up for the down payment on an apartment with a 30-year lease basically requires being able to hold a reasonably high-paying job for 3 years. Real estate is definitely way overpriced, but it's not exactly insane either.
Housing is also a root cause of a lot of other issues. Equity. Environment. Health. Upward/downward mobility. Ethnic integration. And so on.
Everybody needs health care. Perhaps there's someone who wins the lottery and makes it through life without a doctor - though most don't get through their very first moments without one - that doesn't seem like something to plan on.
Also, there are non-illnesses, such as giving birth, where a doctor is needed.
And there are accidents ...
