AFAIK this distribution of expenses is why "Medicare for all" isn't that much more expensive than just "Medicare + Medicaid" (which is to say, public health care spending as it exists already). Consider also how many of the most expensive younger folks, being the ones with major chronic illnesses, are already unable to work and on Medicaid. Everyone else is relatively healthy, on average, and so pretty cheap to cover. I'd bet by far the largest remaining expenses among that mostly-healthy-and-not-already-covered-by-public-programs segment are pregnancy, births, and first month or two of care for sick or premature newborns.
