Found something - a PDF file that I'm not sure about how to link to. Below is the link to a Google search, and the pdf file is entitled "Budget of the United States Government - Historical Tables"

link below may give the pdf file directly. If not, I guess it canbe truncated to the site.

I haven't read this all, due to and on account of me being a bit ambivalent over reading very long documents that cover the entire history of the budget, with header-notes, section notes, and no doubt footnotes, going all the way back to the first 60 years as a nation during which time "... cumulative surpluses and deficits yielded a net surplus of $70 million."
However, this document is very well-written, beginning with definitions of arcane budgetary terminology, and has interesting data. Apparently (as I suspected) recent years 1950-1976 have seen the category of "programmatic mandatory spending" (largely social security and medicare) double as a percent of GDP to 10.6%. Unemployment was
1.1% of that in 1976, a recession year. Since 1975, it hasn't gotten any better.
There may be estimates of projected funding deficits to programmatic mandatory spending but it looks like that category may programmatically sink the nation - not to mention States that are biting the bullet, perforce.
This is serious stuff guys. Just glancing over the data it doesn't appear we can grow our way out of it. The nation has grown itself out of wars, because those end.
