...the poor in the US are (for reasons I certainly can't explain, but there might be studies that explain it) much more likely to be unemployed....
Right there is evidence that you don't understand the US or capitalism enough to be commenting on ANYTHING (the fact that you cant explain this stuff).
Let me fill you any a little, the reason that the poor are "much more likely to be unemployed", it's not that they are unemployed because they are poor, its that they are poor because they are unemployed. DUH.
and much more likely to be criminal. They're also much more likely to abuse drugs,
being a criminal or drug abuser is looked down upon in our society, this it is harder for chrimals and drug abusers to find jobs, and when they are lucky enough to find jobs, they certainly don't excell at their jobs - thus the poor are poor BECAUSE they are criminals and drug abusers.
and they get less average food per year than their poor European countreparts.
Does that explain why the average poor American happens to be overweight?
The American poor are also more likely to die of diseases like the flu, diabetes, terminal illnesses (cancer, AIDS, etc.) and epidemic diseases (like cholera, anthrax, Mad Cow, ecoli, hepatitis).
Sure, thats the downside of being poor, you don't get as much stuff, including medical care, as rich people. If it wasn't like that, then the poor wouldn't be poor and the rich wouldn't be rich. It's SUPPOSED to be that way.
The poor in the US tend to live in isolated high-crime "ghettoes", whereas, with the exception of megatropolises like London and Paris, the European poor tend to be intersparsed among middle class families.
And what does that have to do with anything? In the US the rich tend to live in isolated low-crime areas. The only thing that I can derive from that is that in the US, poor people commit more crimes that do rich people.
The US poor tend to drop out of school at an earlier age than their European countreparts, and as well, the US poor are overall more likely to drop out.
Yes, educational level definately has something to do with income earning ability. Isn't that the way it is supposed to be? Do you really thing that high school drop outs should make more that doctors?
As for where the extremely poor are, that's divided between the rural poor, like in Appalachia, and the urban poor, in inner cities like Los Angeles and Baltimore. Why aren't they being helped? I would probably point to the political gridlock in Washington as a cause.
I've be to LA and Baltimore before, and just got finished with a trip from SC to Indiana, much of it through the Appalacians. I didn't see anyone starving to death in any of these places. Why do they need to be helped? If the nature of their poverty is their location, then wouldn't the only "help" that they require would be to relocate them? I've moved several times during my life and I don't seem to recall ever having to have a special permit to move.
