Take a look at income disparities worldwide and you'll see a common thread with every one of them. The countries with the smallest income disparities have the greatest levels of satisfaction, education, health outcomes, the lowest incidences of drug use and teenage pregnancies, lower incarceration rates, and an overall higher standard of living for it's citizens."
That's a pretty general statement. I don't know what countries you are talking about? Not only that, how do you know that income disparity is the cause of all the problems you list? Things like this are never as simple as some people make them out to be. Also, and this just my personal view, but I really don't trust most studies and statistics. Why should I? There's too much influence in the way most studies are funded. Add to that the current political environment, and I see nothing but the potential for bias.
"We are no where near the top and if remember, near the bottom of the middle rankings."
Someone should tell the millions of people tunnelling their way into our country, or climbing over the walls this. Maybe they'll try to get into one of the "good" countries on your list.
