There is a great book you should read called Treasure Islands[0]. It's equal parts fascinating and infuriating, and makes you realize the system has never been set up fairly.
Rich people have always had their own financial systems that are outside of, and one step ahead of, the regulations and rules the rest of us are subject to.
Reminds me of a quote from the film The Usual Suspects-- "The greatest trick the Devil ever pulled was convincing the world he didn't exist."
The system remains that way in part because a large number of people are duped into believing it is in their best interest to keep the system in place, despite the minuscule probability of actually benefiting from it.
The book shows that a lot of the people who sustain that system (by writing the laws we are all subject to, but leaving convenient loopholes in them) do actually benefit quite a bit.
