Men AND women, boys and girls need to try as much as possible to procure a hobby (or career, if possible) that involves owning a MEANS OF PRODUCTION. That is, being able to "create" something from relatively cheap raw materials. For example, making rope from tree bark, clothes from cloth or even old clothing, food from seeds and a bit of dirt, sheds from lumber -- you get the idea.
My point is that everyone should try to NOT just "work for a company" because if you can't point to what you produce, your job is in danger. Period.
If you can't "gracefully degrade" your current job into selling it door-to-door at a slightly discounted rate to help feed your family/pay the bills -- you need to look at a different line of work -- at least in your spare time.

A plumber could hawk his services door-to-door if he were starving. A construction worker could knock on my door and make an offer I couldn't refuse to build me a new shed. A mechanic could fix my broken weedwhacker and feed his family for a day if he were frugal.
If you couldn't do something similar -- reconsider your current career. If you need others -- or your company's $100,000 machine -- to help produce some end result, or if you have no idea what the end result really is -- you're in a vulnerable industry that could send you and hundreds of others to the unemployment lines for no fault of your own. Likewise, if you work in a service industry that you could easily picture people living without (hair styling/coloring, beauty salon, etc.) you might not be able to survive a serious economic downturn.
I think some people work at jobs wherein they basically react like a man who found a hole in the ground spurting out dollar bills:
He would dance around, excitedly, singing "I don't know how it got there, or how it works, but I'm one happy camper!" and he would proceed to go to work every day and milk that cash cow, trying not to ask too many questions!
But if a person of average intelligence can't trace where the money is coming from -- how your "paper pushing" is able to be traded for financial support to the tune of $50,000 a year, for example -- there is a possibility it's not founded in reality and reality might come crashing down upon you at any time.
