“There is no different handling of taxable income below $17400, no different handling of taxable income between $17400 and $70400”
Okay, but there would be between $17400 and below and from $17400 to $70400. That is to say there are different rules for those different groups. Why you can’t sen to admit there are different rules based on what bracket you are classed in is beyond me.
“I don’t think you understand how the tax brackets work”
Freeze right there. So you admit brackets exist. Let’s work off that. You would also agree that different brackets are taxed at different rates. Which means different rules apply to different brackets. Which is to say the law operates unequally on people based on what bracket they fall into.
