Let me also say that I support at least a $10,000 standard deduction. Really, $15,000 would be better so all full time minimum wage work would be tax exempt. The proposal should be revenue neutral when adjusting for the standard deduction component.
If the proposal still doesn't shake out toward neutrality after a hefty standard deduction, rate cuts should go toward the 15% and 20% brackets.
I would support that; I was stupidly thinking about the fact in the UK income tax starts being paid at £10,000; which probably equals out to $14,000
