Yell,
That may be true, but it's irrelevant. Imagine a guy $100 in income and a hundred people with $2.00 in income. If the tax rate is 50%, ofc the top earner is going to pay 50% of the taxes! But is that income fair or healthy for the economy? Most certainly not.
One fact check for you. The economy of the 1970s resulted from a supply-shock, not from high taxes on the super rich.
Adrius,
It's unfair to look at wealth by top percentage of income. For example, if you had a population of 1,101 people where:
1 person earns $10,000.00 = $10,000 by class
100 people earn $100 = $10,000 by class
1,000 people earn $10 = 10,000 total by class
Although the total income of that population is $30,000 and each class is responsible for 1/3 of the society's wealth, this society is hardly healthy. Although the second class lives decently and makes 10x as much as the third class, it is foolish to call them "rich." Look at the #1 person who makes 100x as much as they do! He is also the one who exercises the real power and can oppress the second class by hiring members of the other 1,000 as thugs!
But in the US, the top 1% of household income makes $1 million a year, and the 50th percentile of household income is 44,389. For simplicity, we'll say the latter is $50,000. The households earning $1 million a year earn roughly 20x as much as those in the 50th percentile. But a person earning $1 million a year may own a small business employing 10-20 people. That millionaire may also enjoy more power than the average person, but its unlikely to even touch the iceberg of power brokers in Washington D.C. On the other hand, those individuals with real influence on power - those with hundreds of millions and billions in assets - have a lot more than 20x the wealth and income of your small-time millionaire.
So when politicians say "lets tax the rich," I am suspicious that what they really mean is "lets tax the people with 6 figures incomes and small business owners while we eliminate competition for the elite because the tax brackets stop at $357,701! That, and we made tax loopholes that only we and they know about!"
I believe that "the rich" should pay more taxes, but not substantially more. They are also responsible for the majority of employment opportunities, and small companies are ofc more efficient. On the other hand, I have no problem if the tax brackets expand to include members of the elite, and the top bracket pays 80-90% in taxes. It would certainly strike a blow to plutocracy and possibly prevent another one from developing.
