If you can stop working for 8 years and not end up on the streets, then you're ultimately working for someone who _can_ stop working for 8 years. This is why less than 10 people own more collective wealth than the poor half of the world population. This is not even considering monopolies, corruption, state intervention, etc.
As for what we can do about it, I don't think redistributing wealth is a great idea. Instead I think we should encourage an entrepreneurial spirit, i.e. encourage people to do what so many in Silicon valley have done: start their own business in their garage. I suspect people find entrepreneurship to be worthwhile despite the risk because their work can translate to profits directly, and they're able to use e.g. LISP instead of Java, make an entire system instead of just writing the tests.
