Final answer:
Street prostitutes face the highest risks of violence and arrest compared to other types of sex workers. Over history, sex workers have always faced serious dangers and lacked protection.
Step-by-step explanation:
Among the various types of sex workers, street prostitutes face the highest risk of harm from customers and the highest chances of arrest. Street prostitution often involves direct contact with customers in public places, which increases exposure to potential violence and legal intervention. In contrast, escorts, brothel workers, and online sex workers often have more control over their working environment and client interactions, which can mitigate some risks. In the historical context, sex workers in various settings, from ancient times to the 19th century, faced significant dangers, including sexual violence and infectious diseases like syphilis, which resulted in considerable suffering.
