You are skipping a bunch of parts there, buddy.
When Ronald Reagan became President, the National debt was less than 1 Trillion. All the wars, infrastructure, social programs, space exploration, we still managed to pay the bills, mostly.
When Reagan left, the National Debt was up to three Trillion.
When Bush left, it was 4.5 Trillion.
When Clinton left, despite posting the last surpluses we had, it was 5.6 Trillion. If we had stuck to Clinton's sensible policies, we'd have seen a reduction
Then Dubya Bush got in cut taxes for rich people (again) put two wars on a credit card, and no big surprise, the Debt doubled in 8 years to 12 Trillion.
Obama, even though being saddled with Bush's wars and tax cuts and getting the country out of the worst recession since the Great Depression, increased the Debt to 20 Trillion.
Trump, cut taxes on the rich and then drove the economy into the ditch... Deficit went up to 28 Trillion. More debt in four years starting with good economy than Obama put in 8 years starting off with a bad economy.
Now, it's up to 33 Trillion. Still pretty bad. We need to do a lot of things to address that, mostly spend less and tax the rich a lot more. But we won't. Borrowing is the path of least resistance.
