Tax cuts for poor people

Rich guys like Warren Buffet think tax rates should rise because they could pay more.
What about the poor people who can't pay their taxes now?
Why doesn't Buffet write a large check and tell the IRS to refund money to needy people struggling with their tax burden?
Where are the poor people writing editorials, saying their experience shows the need for lower tax rates?
Right. They are too busy working to make ends meet.
Too busy to hear politicians claim their burdens as their own, when they cause plenty of burdens on the poor and lower middle class.
