No news to anyone who has been following this for about say the past 20 years or so. If you want a real breakdown on who pays what, here you go: 

Top 1% (AGI average = $480K) pay 39%. 
Top 5% (AGI average = $195K) pay 60% 
Top 10% (AGI average = $138K) pay 71%
Top 25% (AGI average = $80K) pay 87%
Top 50% (AGI average = $39K) pay 97% 
Bottom 50% (AGI average <$39K) pay 3%
Middle 25% (AGI =  >$39K but <$80K) pay 10%

And liberals say that the "rich" do not pay their fair share of taxes? Phhbbbbttth!
