How exactly do you mean this?
The U.S. spent $90.5 billion for "Elementary, Secondary, and Vocational Education" in 2021* (a subset of "Education, Training, Employment, and Social Services"), which is 1.3% of $6.82 trillion in total 2021 government expenditures. Compare to $696.5B for Medicare, $754.8B for National Defense, etc.
If anything, this illustrates how relatively unimportant a base level of education is in the U.S.

My state of Washingon spent $17.5 billion on schooling this year, on top of that federal funding.
That looks like ~28% of the state budget, and per-student spending appears to very high (the 4th highest in the U.S.). Washington is spending 1.5X per student as compared to California, and is apparently not seeing commensurate improvements. I wonder if there are folks working on debugging the apparent inefficiencies of state education systems.
Per the US Department of Education[0], the US spends 34% more per student than the OECD average. At the post-secondary level, the US spends double the OECD average.
