Reagan did far more damage to the United States after he left office
How exactly?
After the extremely charismatic Reagan left office, a powerful, toxic narrative has lingered - that tax cuts are great for the economy, that government always does everything wrong/inefficiently, and that regulation is bad and anti-american.
From that philosophy, we've gotten huge deficits. a spike in inequality, a democratic party largely unwilling to do anything about it, and most of all, the worst financial crisis since the great depression.
