Actually, from an economics standpoint, not bailing out AIG (or any of the other "too big too fail" firms) would have been better.
First of all the "money" wouldn't have been lost forever. The devaluation of the portfolio and corporate assets would have been absorbed by other firms who took over those particulars. The "funny-money" or the inflated investments would have simply adjusted back to the proper amounts. So its not gone forever, that is an erroneous economic perspective.
Secondly, yes, some people would lose their jobs. That is a short-term problem that would have allowed the high-value talent to move to other firms or simply find new work. Not everyone is guaranteed a job for life in a free market economy. While some would have lost their jobs they would have found new jobs, most of them in the proper sector, and probably found better jobs. For those who were complicit in the company's demise they would learn a valuable lesson and be moved away from the ability to harm future firms. Though the short-term difficulty would have caused stress on many, the longer term benefits would provide a more robust and stable result.
Third(ly), yes, the company should have been allowed to go out of business.
Why was AIG saved and not Bear-Stearns? Guess what, I betcha almost all those folks from Bear-Stearns have found new jobs within a short period of time. I don't see people with Bear-Stearns shirts wandering around Wall-Street aimlessly looking for work. Just like with Bear-Stearns, if AIG had gone under other firms (stronger firms) would have stepped in and provided capital, jobs, and a network for the clientele lost from AIG. The world wouldn't have ended. A bunch of stuffed shirt individuals would have simply been put out on the street for a couple of months. However, AIG's assets and clients would have been passed around and absorbed. How is Bank of America-Merrill Lynch doing btw?
Fourth, you're overestimating the trouble the collapse of AIG would have on pensions and retirements. This is a common tactic in people who don't fully understand the nature of the pension and retirement systems. The pensions would have survived, though depreciated. The 401ks are pegged to a portfolio which would have rebounded. It would have been tough, absolutely. But we aren't promised a rose garden then are we? I mean what's your alternative? Controlled markets? That didn't work too well for the Marxists and Maoists. Bailing out companies is tantamount to a controlled economy. It doesn't work.
Finally, our markets would have been better off in the long run. Short term bailouts prohibit appropriate market correctives that will, in the end, provide the foundation for several decades of substantive fiscal growth. Why do you think the post-WW2 economy was so robust and so stable for three or four decades? It had a lot to do with the weak, debt laden firms being closed in the Great Depression and then a new economy was able to emerge.
The markets are harsh. They tend to get this way when corrupt people leading institutions at the foundation of the economy act inappropriately. As a result these leaders and institutions need to be culled from the herd and replaced. This is part of the process of a free market economy.
When we operate a free market economy appropriately we see significant economic benefits bequeathed upon generations of people. Think about the economic picture for the world 200 years ago...now think of it now. I think we're doing a lot better, primarily because of the advanced economics that result from the free market system.
Oh, btw, I said something similar to this in another thread you posted. Then you disappeared (probably for a good reason) so I'll bump the thread and await your reply there and here. Here's the link:
