Easycheese;
If we look at american history, we have several examples:
After the last time the rich had their way with the american economy (the roaring 20s followed by the j.p.morgan great depression), we put a very high tax bracket on (and ONLY on) the amount any individual took home in pay (not at all to be confused with business profits/income (those who tell you otherwise are lying to line their own pockets.)) It varied in percentages from 70 to 90 percent, and only on the amount left over after the first (in today's dollars) 3.5 million dollars a year. The amount below that was taxed at a more normal income tax rate. The results were lovely; those in danger of straying over making 3.5mil(inflation adjusted) dollars a year went out of their way to dodge paying the extra taxes by investing the difference; in their own businesses (resulting in better pay and benefits for their workers, more stable businesses, etc) or in tax deductible things like charities, commons investments, et cetera where the funds did just as much good.
This status lasted from about the mid 1930s until 1980 when Reagan slashed it down. During this time is America's measurably best, most stable years. There were no bank runs, no economic crashes, people could afford to raise a family on a single income AND take time off AND retire AND eat and play healthy.
Since that time, lower tax rates have allowed the upper crust to abscond with the difference. Since that time, deregulation has allowed them to hoard finite wealth, launder it through offshore loopholes, hire next-to-slave labor in desperate foreign nations (thus culling jobs here and making us more desperate in a very ugly race to the bottom), and so on and so forth.
Right now, even Buffet walks around with virtual ?s over his head, proclaiming the oddity of the fact that, as a capitalist, he pays less than half the tax rate than his secretaries do (15% vs 32-35%.)
Meanwhile, if the tax were even paying THAT much (i.e., the same upper 20s to low 30s I pay) social security would never ever fail, education would could be free-to-all, debts would be minimal and manageable, wealth would still be in the hands of those who spend it (and thus create demand for *duh duh duh* JOBS (which further fuel demand for more jobs which fuel demand for more jobs which fuel demand for more jobs which fuel demand for more jobs which fuel demand for more jobs which fuel demand for more jobs which fuel demand for more jobs which fuel demand for more jobs, ad nauseam.)
So yes, while all I've done is use fact and logic to make my point (in contrary to your accusation) these people really do deserve our vitriol since they are, through their greed, machinations, bait-and-switches, manipulations, lies, etc, essentially raping the citizenry of this country and leaving them battered and bruised and exposed to hostile elements as a result. I and 99% of us have every right to be upset about that.
Are you really suggesting that 3.5 million a year is not enough to live on? Are you really suggesting that 3.5 million a year does not make one very very very wealthy. Because it was that at that (soft) limit (since someone could choose to take more home if they wanted to pay the higher tax bracket) that America thrived more than at any other time in its short history. If you want further evidence, look at any point throughout human history where all the wealth was held by the few, and see how that turned out.
Next thing, you'll be telling us 'let them eat cake!'
