To Kelvin, trying to understand your logic: just because the rate of increase diminishes as you move up the scale, it means that the poor are being taxed to feed the rich?

One of them earning $500K contributes more tax then 10 of us earning $100k.

Based on the chart, the former pays about $80k (@16%), while each of the "poorer ones" only pays $7k (@7%). Yet, the salary of the former is even near 10x that of the "poorer ones".

How's my maths?
