Assuming your statistics are accurate, I have two questions:
If the richest 1% earn only 10% of all total income, how did they accumulate 50% of all wealth?  Stock options?  Inheritance?  A heavily utilized penny jar?
What is the actual tax rate for the 1%?  After, of course, their expensive accountants have made use of every tax loophole that exists for those who can afford to exploit them.
