&gt;<i>under those working conditions</i><p>Why do you assume those are the only working conditions possible?<p>&gt;<i>your new lifestyle necessitates that others have to fill in behind you</i><p>My lifestyle doesn&#x27;t &quot;necessitate&quot; anyone to do anything. I buy solar panels because they are available and I can afford them. If all of a sudden nobody wanted to work more than 10 hours a week and solar panels were not available or too expensive, I would not buy them.<p>What each individual does with their time is up to them. When the world changes because of how people spend their time (i.e. stuff might get way cheaper, or way more expensive, or self-driving cars may or may not become a thing), I, and everyone else, will continue to re-evaluate their choices about how they spend their time, and adjust accordingly.
