While we're all obsessing over the tsunami of human misery in Japan, it is important not forget the very real personal anguish of America's least-fortunate fortunate...

More than four out of ten American millionaires say they do not feel rich. Indeed many would need to have at least $7.5 million in order to feel they were truly rich, according to a Fidelity Investments survey.

[...] "They compare themselves to their peer group ... and they are also thinking about the long period they will have in retirement and want more assets" to fund their lifestyle, said Michael Durbin, president of Fidelity Institutional Wealth Services.

These hard-working, long-suffering, economically-anxious less-than-7.5-millionaires... these are America's new middle class. And the growing income gap between them and the really, really rich is tearing our nation apart.
