What have we learned in 2,064 years

"The budget should be balanced, the Treasury should be refilled,
public debt should be reduced, the arrogance of officialdom should be
tempered and controlled, and the assistance to foreign lands should
be curtailed lest Rome become bankrupt. People must again learn to
work, instead of living on public assistance."

- Cicero - 55 BC

So, evidently nothing.
