> Once you reach the level of technology that can provide for everyone, what need is there to make more?
Because you can never reach that outcome no matter what your technology is.
Your premise is so vague as to be useless. Provide what for everyone? How much for everyone? Who decides how much for everyone? Based on what? Elected by whom?
If you actually dig into any of that what you'll find is that it's impossible. Unless you use a hyper violent authoritarian model that dictates every minute of every person's life. Otherwise, one person will always have different needs than another person, without exception (and that's so varied we could be here all day listing the differing ways, from freak health situations to genetics to activity choices).
And that's just on matters of basic needs. Then we get into luxuries, any and all things people want beyond basic needs. And then you have to debate the extent to which people require some manner of luxuries beyond basic needs in order to actually continue to exist in a healthy manner. And then you have to get into who decides on that, who dictates which people get which luxuries, if indeed it's decided people require some level of luxury in their life.
And that's just scratching the surface at a minimum for why the premise: once technology has provided for everyone - entirely implodes upon any inspection at all. It never can, it never will. Human desire is infinite up to the point of expiration. That includes the desire for new experiences (can people live without new experiences? doubtful, certainly they'll live horrific miserable lives without such), which is a gigantic envelope of things unto itself, beyond the basic needs category. Who decides what new experiences everyone has access to? How much allocation to that? And on and on and on it goes.
