I don't disagree with parts of what you say. However, the idea that today's poor are worse-off I think is wholeheartedly, incredibly wrong.
Does society have issues today? Of course! There are an incredible number of issues. But I believe that the data support that on virtually every metric we look at, we are living in the best time because through technology and social progress. Have some of these advances come at a cost, of course. Do some of these advances have hidden costs and maybe they're not so great? of course. Are there rent-seeking assholes who have pseudo-stolen wealth from many, of course.
Still, I'm not sure you can make a credible argument that poor today are worse off on any large time scale.
