Notice how after 2000, since the implementation of the BUSH cuts, the median income has shrunk. AWESOME!
I have no idea what you want to "prove" showing these graphs.
You may of course remember that Bush wasn't president in 2000, when the last recession began and his first tax cut arrived only briefly before another event that seriously hurt our economy for at least a year - 9/11. Aside from recuperating from that event, the entire hospitality and airline industry suffered, we began fighting in Afghanistan and began implementation of greater security with a newly created Homeland Security.
Secondly, your first chart clearly shows a recuperative period following every recession - that is, after the recession ends, the effects trail afterwards. A recession that also shows began before his term.
Lastly, your other chart demonstrates something we have actually discussed before - the GINI index of this country has increased over the last forty years, although it's debatable how relevant it is. But you will also notice that the highest percentiles have been growing steadily without any correlation to who is in office, or who controls Congress - the rich got richer under Johnson and Nixon, under Ford and Carter, Reagan and Bush, Clinton and Bush. It's got very few bumps, because their policies have very little to do with it. So its relevance to this discussion, while interesting, is totally immaterial.
