they will always exist. they've existed for over 100 years and a mere 30 years won't change a thing. in all reality the mafia hasn't died they're still pretty strong to date. just because they're not making as much noise today as they once were doesn't mean they're dying. that just means they're much more in the shadows today than they were in 1990s. so they'll probably still be around in 30 40 50 60 70 80 90 more years.
