People lived less luxurious lives, and so even on tiny, pitiful wages, they found they were living better than they used to just by being "employed".
But the runaway affect of this form of society resulted in what effectively was EVERYONE living in luxury. I don't mean gold toilets and cavier and champagne for breakfast, I mean the things we take for granted, like constant running water, electricity, food from any season from all over the world, multiple cars, advanced tech in our pockets, etc., that was what the result of it was. It's to the point where you can go into a shop and buy a whole cooked chicken for what would be maybe 30mins of work in currency terms, which is mad when you think about it.
The issue wasn't that we all are living too comfortably now compared to what we used to, the issue is that the wealthy became frustrated that their style of life was no longer better than everyone else's. So they created grander and grander levels to reach. To do so, they needed to keep more and more of the wealth, and one way of doing this was that influx of poor foreigners to do the work more cheaply.
This in turn is affecting us by not only increasing the ceiling for the wealthy, but actively lowering the floor for the average worker. We have further to try to climb if we want the luxury we used to have (homes, cars, a family on a single income, etc), meanwhile the really wealthy are wasting money racing each other to space.
