The effects of the new deal is not only a very complex subject, but also very -very- politicalized, so I doubt you can find a really good unbiased analysis of the subject.
Here's my POV on this topic, one I hope we can find consensus around:
1. The US Government needs to restore confidence in the banking sector.
2. The US Government needs to get involved, in a public (although not necessarily a major way) to restore consumer confidence.
3. The US Government needs to encourage foreign trade and deal with Smoot-Hawley
4. Prohibition is going down; some kind of gains will be made by ending the ban on drinks.
5. Much of the US Electorate is going to be encouraged by nothing more than the a "BOLD GOVERNMENT INITIATIVE" or six. The US Government simply weighing in on economic affairs after the lassiez-faire failures of the 1920s would go a long way to soothe the fears of the American People.
6. Economies work in cycles; some kind of upswing after 1932 is happening no matter what.
I think these six points are solid enough. Some of these programs are indeed total hogwash--agricultural subsidies and paying people not to farm is pretty much indefensible; banning child labor is clearly the right thing to do. But I think that any US administration in 1932 is going to play by these six points and thus avoid a Long, Lindbergh or other dorked up presidency.
