This is a question I need to answer carefully, since "good" involves value judgments that reasonable people disagree on based on their political priorities and values. Rather than giving you my own verdict, let me lay out the major areas of his record so you can weigh them yourself.
Economy
•Unemployment stayed historically low through most of his term, and the economy added millions of jobs post-pandemic recovery.
•Inflation surged significantly in 2021-2022 (reaching 40-year highs), which became a major political liability, even as it cooled by 2023-2024.
•He signed large legislative packages: the Infrastructure Investment and Jobs Act, the CHIPS Act, and the Inflation Reduction Act (climate/healthcare/tax provisions).
•Critics argue pandemic-era stimulus (American Rescue Plan) contributed to inflation; supporters argue it prevented deeper economic damage.
Foreign Policy
•The withdrawal from Afghanistan in August 2021 was widely criticized, including the chaotic evacuation and the deaths of 13 U.S. service members in a bombing at Kabul airport.
•He led sustained U.S. support for Ukraine after Russia's 2022 invasion, rallying NATO allies.
•His handling of the Israel-Gaza war after October 2023 drew criticism from multiple directions — some felt he was too supportive of Israel, others felt he pressured Israel too much.
Domestic Policy
•Student loan forgiveness efforts were partially blocked by the Supreme Court, though he pursued alternative relief programs.
•Appointed Ketanji Brown Jackson, the first Black woman on the Supreme Court.
•Border/immigration policy was heavily criticized, including record numbers of encounters at the southern border; he later implemented stricter asylum restrictions.
Personal/Political Factors
•Concerns about his age and mental sharpness grew throughout his term, culminating in a widely-criticized debate performance in June 2024 against Donald Trump, which led to him dropping out of the 2024 race.
•His approval ratings remained relatively low for much of his presidency, particularly after 2021.
Bottom line
Whether this adds up to a "good" presidency depends heavily on what you value — economic management, foreign policy outcomes, judicial appointments, immigration policy, or his capacity to serve. Supporters point to legislative achievements and economic recovery; critics point to inflation, the Afghanistan withdrawal, and border policy. If you want, I can dig deeper into any specific area — like his final approval ratings, a particular policy, or how historians are currently assessing his legacy.
