The original comment I responded to compared the average American to the average citizen in the "developed world". I'm using OECD countries as a proxy since the term "developed" is ambiguous. But comparatively, US workers are only slightly above the OECD average in number of hours worked per year (1,781 vs 1,763).
>The US bottom 25th percentile earn less than 1/2 the 50th percentile.
Again, only considering the average American here. I would agree that it's worse to be poor in the US compared to a lot of other countries due to fewer social safety nets.
