This calls for more than an attitude adjustment, it forces us to rethink how institutional memory works so that in another 80 years we don't forget all over again. (I know 'Remember AIG' doesn't quite have the same ring as 'Remember the Alamo' but we can work on it.)

Great Comments. I do think there are people around who have values and are trying to teach the next generation - I suspect (as is common) that they are not the noisier elements in society.
(I have just come from a conversation with my 8 year old about the cost/benefits of joining Club Penguin - basically if the lad wants it he can pay for it himself!)
Fred although I think there is some truth in what you say I also believe that we emphasise different elements in society at different times. rather than one type of person simply disappearing.
One thing that still disturbs me though is just how embedded credit culture is in our society and this does not seem to reducing (getting worse if anything). More and more connectivity deals seem have a "free" laptop with them. You generally don't pay the full cost of a mobile phone - you buy that on a form of credit (call charges over time). "Interest Free credit" is another one that sickens me (basically if they can afford to not charge interest they could cut me a better initial deal). Rather than reducing (as I stupidly thought) with the credit problems - it seems to be getting worse.
Probably the most valuable thing we could teach children is not values (only kidding!) but how to calculate interest payments over a 20 year period......

Trevor--somewhat agree, but remember that I will teach my children MY values, not YOURS, or those that someone (who means well, but...) decides I should. Be a role model for your own, but let others decide what is best for them and theirs. I fervently decry the growing prevalence of the socialist nanny-state and forced sense of "community" now being espoused by those who only have the best interests of "our children" at heart. I shall, therefore, teach my children to rail and fight this at every turn and be a proper role model for them to follow.
Judith--yup, it's GONE. Get over being mad at (insert today's villains here) and get on with the rest of your life. Pay attention and you won't suffer so much the next time it happens. And it most certainly shall happen again. No amount of "after the horse is gone" regulation excess will prevent someone finding the next scheme. As Mark Twain said, "nothing is fool-proof because fools are so ingenious."

Useless Sam - I reject the premise that nothing will change. This is exactly why "fools" continue in their "ingenious" schemes and WE ALLOW them to do so. As I said, this seemed like a designed perfect storm. One of the biggest problems is how we define and revere some and denigrate and debase others--all being criminals though some escape sentence while others go straight to jail for what some see as far lesser crimes.
It's not that these guys are ingenious; they count on our limited memories and desire for quick fixes. Instant gratification is more important than reform; a return to the same is often preferred in such a time, thus giving those in power continued power without demanding reform through various means. A criminal is a criminal ingenious or stupid. Geithner's call for a risk regulator is important. But, of course, who will appoint and watch this one will be important.
Motive matters in such behaviors as well as the ill effect on society. Clawbacks, lockup, and community service are necessary. Put their "ingenuity" at work in an inner city or rural area under ball and chain--not really. Do not speak to me of silenced anger. "Be angry and do not sin." (Ephesians 4:26)
By the way, whose money is gone?

'Be a role model for your own, but let others decide what is best for them and theirs'
Useless Sam - I say Amen to that my friend .... and speaking personally I hope I've taught my 3 children more about values than I have about money :-)
