LTCM would have clearly been "not bailed out", except it was. Admittedly not directly by the USG/FR, but at the direction of the Federal Reserve.
But this model does hurt the little guys. Since Canadian banks form an oligopoly, they charge you for lending them money; account maintenance fees are standard. This hurts the smallest savers the most. Similarly, there is minimal competition in setting interest rates. Finally, financial innovation, done right, does help people---think Vanguard, index funds, ETFs, etc. All much more limited and much more expensive in Canada (I think).
In contrast to Canada, I think we would be better off with many small institutions, lightly regulated. Then they can compete for your business and do not need taxpayer support when they fail. When they become too big, break them up.
