1. Don’t automate (so that there are plenty of jobs for all). This is an obviously silly idea since it results in the sort of shitty build quality and strikes that the seventies were famous for.
2. Automate everything that can be automated and incentivise people not to have children - thereby reducing the population and hence the demand for jobs. Get the population of the UK down to 30 million or so and we could be self-sufficient (if necessary), and a lot greener. We might even build up some eco-credits so that we can continue to enjoy eating meat and driving cars and doing all the fun things that we’re occasionally told we have to give up for the good of the planet. Personally, I agree that we need to fix the planet - but the easiest and best way of doing that is to stop polluting the world with more of us. More than two children? Punitive tax (or sterilisation for those who can’t afford the tax). No children by the time you reach retirement age? Fat bonus in your pension. And with increased automation we don’t even need to worry about a shrinking workforce - because that’s one of the objectives that we should be seeking to acheive.
