Much is made by some MAGAs that Donald Trump claims to donate his $400,000 annual salary.
What goes ignored is that Trump sucked $7.8 trillion of debt out of the economy during his first presidency.
Trump's One Big Beautiful Bill is estimated to add another $3 trillion to the debt.
In order to break even, Donald Trump would have to remain president, and donate his salary,
for the next 27 million years.
And we are only less than six months into Trump 2.0.
In the modern era, every Republican president has exceeded the deficits of his Democratic predecessor.
Always remember, Bobby, Republicans are the party of fiscal responsibility.
Doing some rough, quick "napkin numbers", USA National Debt was
@ $19.7 Trillion this date in 2016, about 7 months before Trump starts his first term.
On this date four years later in
2020, USA National Debt
is at @$ 26.4 Trillion, an approximate gain of @$6.7 Trillion. A bit short of your "$7.8 trillion" claim.
On this date five years later in
2025, USA National
Debt is up to @$37.0 Trillion. !!!, That's about $10.6 Trillion gain and less than $2 Trillion would have come from Trump's last six months of his first term and the current@5 months of this one. Looks like about 8.5 -9.0, at least of that increase is Biden/Democrats so appears Biden/DNC out spent Trump in Joe's term versus Donald's term. In other words the Democrats/Joe Biden were bigger spenders and debt makers !
Now projecting ahead to this time in
2029, when Trump is out of office and not sure who will take his place, the trends in spending and debt show we
will be at about $46.8 Trillion. A gain of about $9.8 Trillion, or average of $2.45 Trillion per year.
Obviously this last is a projection, and assumes no major cuts in spending and programs as we go through the next four years. But that might change plus or minus ...
Also, need to remember that it's Congress who make the budget, and a POTUS either signs off on approve, or if not, and waits till the fiscal year's funding runs out with not signing, then parts of the Federal government start shutting down for lack of funding.
So there's some numbers and site links/references for all to consider, and a lot more information than you provided.
The DebtClock.org has a "time Machine" function which takes back to 1980, so one can see how there has been an exponential growth curve that is fairly consistent no matter which party in is the White House.
