Unfortunately, capital/corporations don't need humans to have an economy. Let's say 1% of the population owns the capital. Then all capital (resources, automation, etc) can be used to serve the 1%. As their wealth grows, and their capital capabilities grow, so may their demand for thing such as space craft or other ridiculously expensive things. The result would be an economy with fewer and fewer people, and yet the economy is "healthy" in that both production and consumption continue to grow. Now add in machines capable of a survival imperative, competing with each other to open up new resources to enhance their long term survival. Now an economy grows without any people. This is the default we are heading toward. I don't know what the best answer is for humans, except to view all humans as retirees, and give future machines the benefit of retiring in the future too, so that both humans and machines are aligned in the desire to subsidize themselves eventually as they become obsolete.
