That would be a much more helpful graph if it was matched with an identically formatted income graph. The top quintile is paying almost 70% (declining in the last decade) of federal taxes according to that graph. However, if the top quintile's income has skyrocketed during the period (which I'm pretty sure it has), then the stable to declining tax share means that the burden has shifted to the lower classes and the rich are getting a free ride.
