For a government to make the same revenue with a linear tax as they do with a progressive tax, this mathematically implies that a tax increase for poorer people and a tax cut for lower people.

Alternatively, you can cut government spending, which normally means cutting services that disproportionately affects the poor.

Either way, moving from a progressive tax to a flat tax is a guaranteed net negative for the poor.

My original point is that corporation do not pay as much tax as they should. The come down from progression should be gradual - as corporate tax holes are plugged, the higher tax rates could be reduced. So that wouldn't affect the poor. It only slightly changes who pays for it.
