re social mobility
A critical fact that is routinely covered up is that the majority of those under the poverty level in the U.S. are there temporarily. It's not always the same people year after year in the bottom percentiles.
that's an interesting point, which I don't know if applies to other countries too - but anyway it's certainly worth noting.
I've already explained my criticism about oversimplification - anyway so long as I'm not regarded as some liberal caricature, I'm happy ..
