I think there's a larger point you're missing because of too narrow a focus, and because of the common misconceptions as to who's rich and who's not.
Increasingly, over the last 30 years, it's been the investor class who's reaped the benefits of our society. Changes to the tax structure, offshoring, financial "innovation", and the purposeful weakening of Labor have shifted income to the tippy-top, and have shifted the source of income from work to investment.
Perhaps we've gone off on a tangent here. It was predictable that as a greater % of our population went to college and took finance and economics courses and learned that investing was the key to comfortable retirement and wealth beyond the basics, that investing would become a priority activity. I'm happy many people invest these days and not just the rich as before.
What you're saying about the 0.01% income brackets may be entirely true -- makes perfect sense. Once you have $10 million in the bank, why risk any of it? Put it all in munis and live a comfortable $250k - $400k tax free lifestyle on the annual interest alone (ask John Kerry and his wife). Of course those with $300 million have considerably higher lifestyles as expected.
Maybe what you're not realizing is that these "top 400" people would have this kind of wealth regardless of the current tax structure. In other words, the super rich will always be rich, and always be part of the investor class. Socialites and inherited wealth don't need to work if they choose not to. Nothing is going to change that.
Anyway, my response had nothing to do with these super wealthy lazy trust fund brats. I was simply pointing out that we used to take responsibility for our actions, pay off our debts, and own up to and correct our problems (at least most of us). Now, my debt is apparently your problem. So is my late mortgage. And my success. And my income disparity relative to yours.
The banks blow themselves up, people take out huge mortgages they have no hope of paying back because interest rates are stupidly low, and we give them all a bailout because we can't bear the thought of the economy self-correcting and weeding out the wheat from the chaff, and taking some innocents with it. This is nonsense! Is the country better off trillions more in debt after the bailouts and socialization of losses? More importantly...what happens NEXT time down?
