I'll use my own taxes.
My AGI was $29,000. My taxable income was $18,600
My taxes withhelf from my paycheck last year was $3,700. I was given a refund of $1,500.
What does that mean? I paid $2,200 in federal taxes. I did not "get it all back"
Looks to me you are very close to the line - It used to be 51% but now its closer to 43% based on what I just looked up. Also, as I said, you do still have to pay into SS. And while most everyone in that bottom group make up all the payroll tax with credits, some towards the top end of it don't quite get there.
I hadn't looked up where the "line" was lately, for that, I admit I was wrong. However, the widespread belief among many that the rich aren't paying enough and we tax the poor too much, to me, seems like complete hogwash.
