Short answer: Yes! The big difference in the US between RICO and earlier laws is that earlier, law enforcement had to catch a crime boss in the act of committing a crime to prove him guilty. That was almost impossible because a crime boss gave orders to people below him to commit crines. But, RICO makes it a crime to be a part of, or conspire to be involved in, a criminal organization. Now, if law enforcement can show that the boss is part of a larger organization directing criminal activities, he can be prosecuted and sentenced to many years in prison. Your Dutch law seems to say almost the same thing.
