Why do people blame the designer for not adding enough lifeboats on the titanic?

People blame the designer of the Titanic for not including enough lifeboats primarily because the ship was marketed as "unsinkable," leading to a false sense of security. The regulatory standards of the time were outdated, requiring fewer lifeboats than necessary for the number of passengers. Additionally, there was a prevailing belief that lifeboats would detract from the ship's aesthetic appeal and luxury. As a result, when the Titanic sank, the lack of adequate lifeboats became a focal point for criticism.
