You have to remember, the BUDGET is written by CONGRESS, or Legislative branch. NOT the President or other Executive Branch entities. The President signs the budget, Congress makes it. The fault for our fiscal problems rests clearly on the Congress, and up until recently it's usually been run by the Democrats, with joint Executive/Legislative branch control by Democrats the majority of the time. It's only been when Republicans, even with Rinos in charge, have had partial or complete control of the Legislature that the budgets have been held even slightly in check, as evidenced during the last 4 years of Clinton and first two years of Bush. Just witness what the House, with Democrat help, did for the last budget resolution, allowing growth in programs rather than just shutting things down and holding the line against future profligate spending.
Reagans tax cuts, as well the ones forced on Clinton and Bush and Trumps first term, were put in place to grow the economy, theoretically growing the country out of it's Debt. But Congress, and the Liberals and neo cons, being greedy and foolish, out spent that Economic growth and established long-term programs that Trump is now KILLING with extreme prejudice. Which, being a Social Security and Military Pension recipient, I totally support and encourage.
