Well, the one benefit of being a mason is that you get to meet a lot of influential or rich people. For example, my family is nobility (The Nizamate of Hyderabad was annexed by India in 1948) , hence, my father rose up to be a grand mason. It really depends on where you live. For example, in London, if you do manage to get in, you'll get to meet royals. In Washington D.C., you'll get to meet a couple of senators. It's the mere fact that influential people that belonged to the masons were involved with the foundation of the USA that the society is considered by many to be part of the illuminati.
Being a mason is no big deal. It's rather boring, actually.
