You seem to have forgotten that the ruling class requires tax payers to fund their incomes. If we're all out of work, there's nobody to buy their products and keep them rich.
Not sure this equation works out. If demand for labor goes towards zero it really means there is no demand. In other words, when AI and robots fulfil every desire of their owners there really is no need for “tax payers”
If you really think 8 billion people are going to not tear the arms and legs off their overlords and their robot minions before that you're completely daft.
