So those taxes on cigarettes are passed to employers for the lost productivity? And the taxes on sugar will be passed to insurance companies?
The answer is of course no to both... so people are being taxed because others are being infringed, but the taxes don't serve those infringed.
Also, diet soda has its' own issues... and more fat people are drinking diet soda than regular.

edit: Also, we don't need to tax soda, just stop subsidizing farming...
