Depends on what they call income. We know we have millions who are receiving their payment in all cash. Millions of others are living entirely on funds from EBT, WICK, housing subsistance, etc. These people would still end up paying nothing.
IMO if we are going to push for changes in taxes all current Federal taxes and fees should be abolished and use a consumption tax on everything but groceries. That would hit everyone.
This is discussed year in and year out...Over and over and over.
The reason this punitive tax structure is never ending and never dramatically changes to the benefit of tax payers, is because the government does not want to do anything which will affect the massive amount of money government consumes.
End of story.
