This would require a massive level of taxation and/or government control of health care considering that healthcare is currently 17% of GDP.
How many households do you think spend more than 10% of their income on healthcare right now, and what kind of households are they?

For that matter, a low-lifetime-income person on Social Security can easily have more than 10% of their Social Security going to pay their Medicare Part B premiums.
