Rat Race is a term used to describe a frustrating, hard-to-break financial lifestyle. It is a lifestyle that is lived by countless people, oblivious to the very nature of it, to a degree that even when called upon, vehemently deny it.
To summarize the Rat Race, It involves subjecting one's self to a time-consuming job, saddling one's self with heavy mortgages/rents, bills, children, and liabilities, forcing the individual to continue busting his or her ass at that same job. The illusion that working at the same job will be better bars off alternatives.
There exists many options for financial gain and exit of the rat race. Remember, the definition of insanity also entails doing the same thing over and over again, in an attempt to make things change.
So, escape the rat race...

.... and find the cache!
