IMO a major deficiency in this calculation is children. Raising children costs money, and families without enough income may not feel that they can afford to raise children, and they may therefore not have children. This means that their income looks better than it really ought to, and it also reduces the birth rate. And, while the US’s birth rate is not catastrophically low, it is below replacement. This may have some negative long-term consequences for the economy.
