The CBO gets their data from the IRS. If you think everyone is lying then point to your own solid analysis based off of IRS data.
The CBO only uses the data they are told to use. For example, specifically the report that you linked to omitted payroll taxes, which make up 34% of all federal revenue (income tax is 42%). When you factor in that the percentage of their income that the rich pay in payroll taxes is vanishingly small compared to the percentage of total income that the rest of us pay, those little bar graphs look completely different. If you factor in total income instead of just adjusted income, it skews the results even further away from what the Tax Foundation is claiming.
See, that's how your citation is useless. The CBO was just doing their job by reporting on only the data that Congress allowed them to use. And that friend, is how you use statistics to tell a lie. It's how congress does it and it's how the "Tax Foundation" does it.
