We don't have a scarcity problem, we have a distribution problem on this planet. The concept of job was relevant when each person had to contribute mostly physical labour to scrape from the earth a basic existence. We're 100 years past that, but are conditioned to believe that not working = laziness.

And when you stop to consider that many of our jobs are derived from immoral endeavors such as militarism, spying on one another, imprisoning others, swindling, producing junk that uses up natural resources, and trading imaginary numbers through financial markets; most of our jobs are quite unnecessary.

However, I can't imagine what it would take for people to seriously reassess their values and the system as a whole.
