I've been fiddling around in Democracy 4, and it's nearly impossible to try to get a $64 Trillion debt under control.
I've tried MMT, & Austerity, Stimulating GDP with Quantitative Easing resulted in Hyperinflation, increasing taxation resulted in tax evasion, & cutting public services prevented me from seeking a second term as I was $2 Billion away from creating a surplus.
On one attempt I was also assassinated.
I'm sure there's a rhythm to solve it but The Debt crisis kicks in quickly.
I'm just curious to see if it's even possible because if it's replicatable in real life it would help avoid a crisis.
