It's also worth mentioning that this principle isn't one that any elected official at the Federal level (Dem or Republican) has.
What we're talking about is taking a somewhat higher percentage if you happen to make more than that arbitrary number. It may seem like I'm nitpicking, but I think the difference between them taking an extra 2% from somebody making $380,000 (vs. 2% less from someone making $379,000) and taking everything over $379,000 is pretty significant.
There is no income level where the govt simply takes the rest, and no one is proposing that.
That's true, just look at all we received from the Injuns. Still working on getting Iraq to donate tho'.
