Any conversation about tax cuts/increases/whatever is entirely pointless unless you show the effective rate curve along increasing income lines. The VAST majority of people pay less than a 10% effective rate. I'm sorry but if you're making $100K and paying 8% (7.64% is the estimate for a family of 4) - YOU aren't paying your fair share compared to my family of four's 31.5%.
Tax rates should be set so that everyone pays and there is a slightly increasing effective rate curve as you progress up the income ladder. Blow it all up and put that in place.
