You do understand that the spending must be less than income before the debt can shrink, don't you? And so, Congress authorized spending has to go down or tax income must go up before the debt can start to shrink. Under Obama, the deficit went down during the last five years in office. The inflection upward after 2016 reflects somebody else's spending. I don't know whose, because Trump plans to increase the debt and so that upward trend after 2016 is not nearly as steep as it would be if it reflected what he said he'd do..
Trump keeps reminding you people that he's doing what he promised. What he promised was to cut taxes, increase spending and increase the deficit much more than the chart you posted as a rebuke to Obama. Congress has control of the budget, so I don't understand why you pin the chart you posted on Obama but you guys always hated the man. I understand. Small minds and all that.
It's so difficult to keep a child's interest. I'm sure you are already bored. Toddle along and build something with your Leggos.
