Everyone should read Galbraith's "the Affluent Society". Our economy is built on scarcity; we couple productivity to consumption (thus, we need jobs because we need to have money so we can buy things so we have jobs). This is idiotic, especially when we don't have scarcity any more. It's very likely humanity is productive enough to give everyone a high standard of living, but our economics don't permit it. We're too busy redistributing income upwards.
Basic income seems a way out, at first. But a post-scarcity economy should be fundamentally different. This likely means getting rid of some forms of property; this won't be easy.
