The source of the national debt and deficit is largely the military spending forced as a result of the war actions of the last decade since 2001. Ask those who oppose increases in taxes why the young and not well to do should be expected to shoulder that cost in the form of a shrinking government and economy.
Someone should repeatedly put forward the question of how those opposing tax increases expected the United States to engage in extended military action since 2001 and not have a deficit for the activity of expending expensive ordinance and technology tactics created by military contractors, and not have a deficit created behind it ??
Pose this question over and over again and see what the answer comes back as.
