I'm rich and part of the financial 1%. I can indeed confirm the rich get richer. I'm not going to enumerate the specific methods, but I do feel bad that middle class or bay area software engineers cannot employ certain financial tricks that only the rich can do.

As a teaser, one important thing is to not share information (i.e. Don't blog about financial "hacks"). Call it a corrupt moral compass or whatever you like, but the fact is this behavior is rampant.
