"whose navy would have trouble with a single American supercarrier group? "
See my comments in the South China Sea thread. They don't even need a navy anymore to deal with our carriers with the DF-21

anti-carrier ballistic missile they've developed and are upgrading. That and they have the second largest submarine fleet in the world, many of which are Russian Akula-class nuclear attack subs.
Anyways, back to the economics, I thank you for at least giving thought to my issues, which is more than what many other members would do. You're right in what the US government did during the Great Depression actually worsened it, but that is because we didn't have the understanding of economics we do today (not to say we have mastered economics by any means). But social security in the modern day is the government forcing you to save in your youth and you collect what you deposited once you retire. Everyone receives the same amount, and I would say the social safety net is a great thing and helps the free market. Savings rates in countries without social safety nets are extremely high - up to 30% - and this hinders economic growth by locking up a lot of money. By having a social safety net you can afford to decrease your savings rate and use your funds more productively.
And again I will concede to you on the fact that many business leaders wrote the economic codes in those times (I don't really have much opposition to what you said in the second paragraph, but didn't want you to think I overlooked it)
Now the bailout is fundamentally misunderstood, because in many cases - Citibank, GM, and AIG - the government is making money off of the bailout funds. I would ask you what economic institutions would be left to pick up the pieces? In the United States alone you were looking at losses to the tune of $300 billion, and that's only from the institutions that were acquired by others after they went into bankruptcy (So that doesn't take into account losses by Citigroup, Bank of America, JPMorgan, Goldman, etc)
