Not all, but a good chunk. Definitely less than half. Somewhere around 18% of current US GDP is healthcare spending [1], growing at around 5% year over year. Education spending is somewhere around 5% of GDP [2]. It's hard to figure out how much actual growth is occurring there since most of the ridiculous increases have been specifically in college, not in K-12 which is the bigger share. Total increase seems to be somewhere below 3% year over year growth. We can even add in military spending and not get to half. Thanks to this year's absurd 9% budget increase [3], military spending is now above 4% of GDP again.

So, healthcare + education + military accounts for around 27% of GDP and about 5.2% weighted average growth for that 27%. US GDP is up 4.2% annualized for Q2 this year, so that growth in our 3 categories is only accounting for maybe a third of total GDP growth.
