Below: always got to include a photo, so here it is - Peace, brothers and sisters. Yes, that's a selfie of my shadow on an outhouse - hey, I liked the photo, so sue me! Click to enlarge (PLEASE!).
Suppose that every day, ten US citizens go out for lunch and the bill for all ten comes to $100. If they paid their bill the way we pay our taxes, it would go something like this:
The first four men (the poorest) would pay nothing. In fact, they would get an earned income tax credit if they have a job.
The fifth would pay $1.
The sixth would pay $3.
The seventh would pay $7.
The eighth would pay $12.
The ninth would pay $18.
The tenth man (the richest) would pay $59.
So, that's what they decided to do.
