Just looking at GDP (in the US), medical expenses do account for more of GDP than housing; however, a lot of those medical expenses come from Medicaid & Medicare, and are not directly out of pocket. I'd love to try to find the % GDP of out of pocket / Premium expenses in the USA as a comparison.

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.

Medicare and Medicare costs may not be out of the recipients pocket, but they are paid out of someone’s pocket.

However, housing costs affect young people more than Medicaid/Medicare, and younger people contribute more to GDP than Medicaid/Medicare recipients. So, when talking about GDP growth, housing is likely much more significant.

One can "just" get a job with good health insurance, whereas homeownership in productive cities has surpassed wage territory (even for professionals) and now requires intergenerational wealth. Helathcare is highly unequal; housing (in job-rich regions) is uniformly impossible for those of us born too late.

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.

NYC has a much better functioning real estate market than SF/Bay Area from what I can tell. With the exception of the remaining rent controlled apartments, there is not an unwillingness to build high density housing. There is a much better match between housing prices and the supply/demand curve.

Not everybody needs health care. Everybody needs a home.

Housing is also a root cause of a lot of other issues. Equity. Environment. Health. Upward/downward mobility. Ethnic integration. And so on.

> Not everybody needs health care

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.

It’s not a lottery, there are a lot of preventative measures. There are however a number of random serious illnesses that could occur, so everyone does need healthcare.

And those preventative measures often utilize health care, from doctor's checkups to cancer screenings to immunizations.

Also, there are non-illnesses, such as giving birth, where a doctor is needed.

And there are accidents ...

No, everybody does not need health care. 90% (made-up as my wife, two daughters and me haven't been to the doctor in 2 years) if not more of health related issues while you are under 40 (maybe higher) can be taken care of through over the counter medications. However, we still require shelter, particularly since we live in an area that is under 32 degrees for 2 - 3 months out of the year.

Obama did push those healthcare legistlations...

Globally, it seems to be the most defining problem, at least that I hear about. Australia, New Zealand, UK, Canada, US are all grappling with "housing affordability".
