That graph needs [citation]s. The source it cites does not mention how they obtained the figures for childcare, and a questioner in the comments asks for, and does not receive, a source for that information. The source article itself doesn't even seem to be the source, it links to yet another article. That article also doesn't seem to be the source, the source appears to be … a politician.

The childcare part — the largest and most problematic benefits cliff in the graph — appears to be specific to PA. But PA doesn't offer a monetary childcare benefit: one would have to be arguing that this is the specific dollar amount that the care is worth … which … IDK. I'd like to at least see that argument. But the vesting cliff, as depicted, doesn't line up with any of PA's cutoffs, either.

So, this graph smells of statistical lies.
