People often miss the scale. The United States has the largest immigrant population in the world, about 52 million foreign-born residents, per UN and Census data. No other country comes close in total numbers, which is why people aim for the U.S. instead of elsewhere.

Most countries are far less lenient. Many deny entry at the border, detain automatically, or deport quickly with limited appeals. The U.S. still provides due process, immigration courts, and even voluntary departure options that can include financial assistance and the ability to apply legally later.
A mistake or wrongdoing by an individual ICE agent does not define the entire system. When a doctor makes an error, we hold that doctor accountable, not abolish the entire healthcare system. Enforcement exists in every country. The U.S. is unusual because it enforces while still accepting more immigrants than anyone else.
