Yes, I realize you weren't referring to state sales tax.
The answer to both points is yes (but it's really not your income that increases but your DPI - disposable personal income or purchasing power).
So, DPI increases, prices fall and government revenues stay the same? And I get a prebate. Still sounds like a free lunch.

No it's not a lunch and it's not free - it's merely simple economics. Read the paragraph in #227 that starts "The answer to both points is yes ..." very slowly a few times and reflect upon what it says. It's something a lot of people miss.
