Not truthful, really. There were many reliefs implemented during covid, with the most significant being the direct stimulus payments and PPP. All combined they cut the poverty rate. It's also important to note that the poverty rate is a measure of household income and while that is certainly related to the amount spent on kiddos, it isn't a measure of the amount spent on kiddos.
Again here, where those dollars were spent are the decisions of the parents. I know quite a few clients that purchased a new vehicle, when that really wasn't necessary, with these benefits. That purchase, which did prop up the economy (one goal of the stimulus), it really didn't provide any additional benefit to the kiddos.
And as a poster already mentioned, the remote schooling has significantly impacted our younger children. Impact that will follow those children, and our society, for decades.
