Shortly after Biden first announced that the federal government would be purchasing 500MM rapid covid tests to give out to Americans for free, a friend told me his kids' school sent home a note to let parents know that they would NOT be accepting at-home, rapid tests to allow children to test back into the classroom after being exposed to covid. Friend was like, "Well, what's the point then?" I'm guessing the point is that somebody's brother-in-law, cousin, or maybe son, stands to make a pile of money off of selling the US government 1/2 billion rapid covid tests. Whether they're accurate, or not, or if they're useful is only a secondary concern. Main thing, Biden wants it to look like he's doing something, anything.
