Since you've already provided skewed expenditures, 4 trillion spent on healthcare, I don't believe using the current proposed defense budget is out of line. 
I didn't "assume" anything, but used federal budget quotes from 2016, which shows quite clearly the income source streams, individual and payroll taxes accounting for over 75%.
You want to increase the "pie", we'll need another half trillion just to break even.
Go for it...
