'There are 130,930 public and private K-12 schools in the U.S.'[1]
$190 billion divided by 130,930 is $1.45 million dollars per school. Now, I will readily grant that a million dollars just ain't what it used to be, but it is, even in 2021, still a heck of a lot of money, and it sure sounds from the raw numbers that public school teachers shouldn't need to spend their own money on basic COVID-19 supplies.
