It doesn’t come close to covering all of it.
There are 3M nurses and 1M doctors in the US. That $100B/yr could pay each $25k in salary, and cover no equipment.
Let’s say we want to pay nurses $150k and doctors $250k, good middle class salaries comparable to tech incomes. You need $700B per year.
That’s not impossible to find at https://www.usgovernmentspending.com/US_fed_spending_pie_cha..., and I think we should—but it’s not obvious how to do so or what to sacrifice.
