Why do you think only steerage passengers were required to pass through Ellis island instead of all passengers?

Steerage passengers were typically from lower socioeconomic backgrounds and posed a higher risk for health issues and potential Immigration violations, prompting stricter scrutiny. They often traveled in overcrowded conditions, increasing the likelihood of illness. In contrast, first-class passengers were assumed to be healthier and more financially stable, leading to a more lenient processing approach for them. This distinction reflects broader societal attitudes towards class and immigration during that era.
