The mid range pays almost nothing. This is also why it’s insane when analysts say all the tax cuts go to the rich. How do you cut taxes on people paying -14% and -5%? Even the $50-100K group is only paying 8% effective income tax.
Even if you include payroll taxes which fund the social security and medicare people get later, the middle income group isn’t paying much. Keep in mind, only the top 10% actually pay enough to cover their social security and medicare costs. Everyone else is getting more than they paid in.
The people screaming for the rich to pay their fair share are the ones paying very little. I bet if you survey the two income groups with a negative income tax rate, they’ll tell you they are paying too much in taxes and the rich need to pay more to pay their fair share.
This is why I’d love to get to a super simple tax system. Exempt income below the poverty line and tax everything else at a flat rate regardless of type of income. Americans are so confused by our tax system they don’t even know how much they actually pay.
