Just for some perspective sake, as well as basic economic sake, let's start with some numbers and data from CBO sources in terms that hopefully many reading here can comprehend.
NOTE: this site provides a series of rolling and increasing numbers on many positive(income/revenue) versus negative (expenses/debt) aspects of our (USA) economy, yet are data~numbers worth examining and considering;
NOTE that this site also offers a so-called "time-machine" function where one can look at the figures of past time-references (NOT adjusted to today's dollar$). This "tme machine" function starts at the past point of "This Day" in 2016 and shows comparable back to 1980, in four year increments.
For example, on this date in 2016, these are the numbers on things like National Debt and Revenues(income) versus expenditures/obligations (outgo~Debt);
Back about several months before MaObama left office.
The similar numbers/data for this time about eight years prior to MaObama taking office are here;
For one example~factor we can see that at this time in 2008 the USA National Debt was about:
$ 9.765 Billion ...
Eight years(2016) later after MaObama's two terms it had nearly doubled to;
$ 19.306 Billion more than doubled !!!
So a growth in USA Federal Debt of slightly more than doubling in just eight years. Of course not all MaObama's doing as there would be a lot of help from Congress that he signed off on, yet still showing hint of a POTUS whom hasn't a clue on how Economics works nor what woul dhave been the responsible thing to do. No surprise one would hope from a POYUS with next to no experience in the "Wealth Creation" side of the Economy but lots of experience on the Wealth Taking(Redistribution) side of the Economy.
BTW, the numbers for this site are from the CBO for the most part.
One of many points being we are going to see the same from current POTUS Joe Biden in racking up similar scale of Deficit and Debt for the future generations to have to deal with.
