I have to imagine that it's pretty rare, and I don't think it's appropriate to generalize from what appears to be a pretty sensationalist case. I expect the laws are usually structured to ensure that children don't fleece their parents out of money and turn them effectively into wards of the state, etc. It doesn't seem unreasonable to me that states would encourage families to take care of each other, though PA seems a bit of an outlier in this regard.
