Because thats how much of your money Obama spent in office. And Trump is going to spend just as much again. That equals $78,553.84 for each of the 119,026,000 households in the country as of September.http://www.zerohedge.com/news/2017-01-04/us-ends-2016-1998-trillion-federal-debt-105464794162691Needless to say if interest rates were higher it would be a lot more than $78k.
Well, as bad as that looks its actually pretty good. People look at quantity without factoring in the actual value of the dollar along with inflation. Donald Trump or any other public official has no control over the GDP.
I would donate it to the government so that it can be used to pay down unnecessary debt.
