Luciano almost abolished the system of "Made Men"

However Genovese pursuaded him to keep it

Although there would have been few objections had Luciano declared himself capo di tutti capi, he abolished the title, believing the position created trouble between the families and made himself a target for another ambitious challenger.[36] Instead, Luciano chose to quietly maintain control through the Commission by forging unofficial alliances with other bosses. However, Luciano did not discard all of Maranzano's changes. He believed that the ceremony of becoming a "made man" in a crime family was a Sicilian anachronism. However, Genovese persuaded Luciano to keep the title, arguing that young people needed rituals to promote obedience to the family. Luciano remained committed to omertà, the oath of silence, to protect the families from legal prosecution. In addition, he kept Maranzano's structure of five crime families in New York City is this accurate?

makes you think how much the mafia would of changed if they did abolish it

Chicago didnt start doing until the 70s. The Bonanno did away with it for awhile when Massino became boss, I think they even made a few members without anything at all, like they just told them that they are made and dont saying anything to anyone about and they were introduced as made members to other members.

Don't trust anything on Wikipedia dealing with organized crime. It can be used as a starting point, but that's all. The paragraph delves into speculation. Maranzano didn't create the making ceremony, nor did he create the Five Families. In fact, there were already five New York City crime families when Maranzano became boss of the Schiro Family. Salvatore DiBella then Joe Profaci headed what is now the Colombo Family; Manfredi Mineo was head of the Gambino Family; Masseria was head of the Genovese Family; and Tom Reina then Joe Pinzolo headed the Lucchese Family. We also have documentation that shows the ceremony existed as far back as the 1870s.

That was from The Last Testament Of Lucky Luciano and according to the book it was Meyer Lansky not Genovese who convinced him to keep it. That book has proven to be a lot of fiction

Luciano had a lot of non Italians that he kept in close company and that he probably held in higher regarded than most Italian made men. Same with Chicago.
