How would you feel if someone taxed you an absolute amount that would leave 50% of your countrymen penniless? And they denied you tax breaks, like the child credit, that they grant themselves? And then that same 50% vilified you to boot?
Nobody said "not fine". You mentioned "economically disadvantaged". Such a person person literally is disadvantaged in some economic ways. Not all. Not most. But some.
You asked how I would feel. That's the answer to that: I'd be fine.
And as I'd be on 3x average pay, the only way a tax break could possibly be large enough to make me not better off economically was if average people get so many their tax rate is negative.
