Soda taxes are also a regressive tax on the poor, as are almost all consumption taxes. Let's see, back of the envelope math: I drink about $5 of soda a week, stipulate a 3% effective tax rate, that implies I 60 cents of soda taxes a month, or less than .02% of my income. By comparison, a poor mother with two kids might well buy $25 of soda a week (three mouths plus they consume it more than I do), paying $3 of sin taxes per week, which could be over a full percent of her income.

The prospect of that enrages me, far more than my opposition to tax increases in general.
