No, it doesn't. Regardless of filing status, they still fall into a certain income bracket. the bottom 47% don't pay that.
What should be done in my opinion:
1) Raise capital gains tax rates to the same as ordinary income rates and eliminate interest carry provisions.
2) Create donut hole on SS taxation. Tax it up to the $128k, then reinstate a 2% SS tax on any income above $500k. That would resolve SS issues.
3) Raise standard deduction to $30k per adult, then eliminate the bulk of deductions and loopholes used in the current tax code by the wealthy.
To be clear, the above doesn't really alter the situations of the lower income as they don't currently pay Federal income taxes, but it would help the middle income families and force more taxation on the wealthy.
I like these ideas. Can you explain though your reasoning for the FICA "donut hole"? And why I now suddenly want a donut?
