Folks can do math - just have to get it into math for some to get it.
One of the problems, is all these bills have charts laying out the costs but at the top, in little tiny print are the words "all numbers in billions". So at a glance, 23 or 476 or 1,189 don't look all that enormous. I think all spending bills should have to list all costs in complete decimal form. When people start seeing pages of 23,000,000,000 and 476,000,000,000 and 1,189,000,000,000 then maybe they might go "whoa, what the heck??"
