Geographically I'm interested in basically everywhere, excluding those places ungoverned by states. Europe, Middle East, India, China, North Africa, etc.

My class just finished reading the Great Gatsby, and I have to find articles about class disparity in the U.S. in modern times and how it has changed since the roaring 20's. It was easy to find articles about how it is now (top 1% own 40% of the wealth, huge gap between upper and lower class, social mobility is low, etc.), but I can't find much about how it has changed. Right now, it seems to be about the same as it was in the 20's. Has there been change? Some possible topics that I thought of are: new vs. old money, social mobility, the american dream, and the gap between the rich and the poor.

When was the development of the American accent and when is it that someone from America would speak English with a different accent from those native to England and the rest of Great Britain?

In the most recent episode of Mad Men, a few characters asked why money was being spent on the Space Program when "there are people starving here on Earth." Was this a common sentiment or was it rare?

In Europe there are cemeteries dedicated to fallen American soldiers. What did countries do with the bodies of fallen German soldiers who were left behind? Cemeteries of their own, unmarked graves?

Where is thought to be located? Are there any trustworthy contemporary sources on its location or a description of it? Is there a chance it will be definitively identified? When was its location lost?

For example, if I asked a Roman citizen in 25 BC what year it was, how would they respond?

I'm very interested in Japanese history; so much so that I bought Japan Emerging as it was recommended on this very subreddit's book list. I'd like a book (or books) about the Meiji Restoration, specifically the buildup to the Boshin War, the rebellions that happened after the Boshin War, and the steps taken by the Japanese government to modernize up until maybe the year 1900, although the Russo-Japanese War would also be a fine stopping point.

Why did he abdicate?

I've read that the Tonkin Incident was staged. And later on the day of that incident day, LBJ addressed the American people to inform them that an attack occurred. This of course lead to escalation in Vietnam.

There seem to be so few.

I am also curious to know what the prices would be with inflation considered. Could slaves only be afforded by modern day millionaires? Or could they also be afforded by a modern day middle class family?

Bonus: How did the shift get justified to the public throughout the transition period?

Was this always the case involving defections? I'm not interested in conspiracy theories, only any insight on how Oswald could defect to to Soviet Union and then return to the West without being penalized. What did it actually mean to defect if you could simply renounce your defection after the fact?

EDIT: I'm not sure why the mods are chewing this post up, a good deal of the comments people have been leaving were perfectly reasonable and by the rules of the sub. It'd be nice if an actual historian would weigh in on this however.

Maybe this is a question better pose to /r/guns, but here goes:

When you look at old military manuals or pictures of soldiers training with handguns they are all firing one handed with their body turned perpendicular to the target. Why is this? You also see it in many depictions of the Old West, the Civil War, Revolutionary War, etc.

It's almost universally accepted nowadays that handguns be fired with two hands for maximum accuracy and control. When did this change occur and why?
