The first one:
Section 1 doesn’t make sense, and I’d rather just repeal the 16th Amendment. Limiting the percentage is good, but repealing it is better.
One of the reasons that people are complacent is withholdings — look at how people act when they get an income-tax return, not like they're getting back their own money but that they're getting money from the government. (ie they completely fail to realize they've made an interest-free loan to the government.)
Another reason for complacency is that because it's done out-of-sight, it's often out-of-mind — or to rephrase it, how pissed off would people be about government wasting tax-monies if they had to consciously pay the bill

The reason I hesitate on repealing the 16th is because I no longer think that a sales tax would be good. With the continual miniaturization and pervasive computing it is quickly becoming feasible to have a progressive sales tax system where the rate you're taxed is a function of your income. (I, for one, see that as a fast track to chips embedded in the hand, which would handle the taxation question — DO NOT WANT.)
