Maybe try looking up the word ‘regressive’ in the context of taxes. I doubt that will happen so here, maybe this helps:

What Is a Regressive Tax?

The term regressive tax refers to a tax that is applied uniformly regardless of income. Regressive taxes take a larger percentage of income from low-income earners than from middle- and high-income earners

So if you really want to fuck over poor people and benefit the wealthy, and obviously Republicans do, great way to do it.
