So long as we have a scarcity of necessities (housing comes to mind) peer competition will ensure that all increases in productivity accrue to the owners of capital, because you need to outcompete your peers for said necessity.

Years ago I outbid some other people for a house in rural Ireland. (This is a longer way of saying "I bought a house"). It was a very cheap house. Those other people have their career choices* (like making pottery for a living vs being a remote software developer) constrained because they were outbid, in the same way that my own choices (like working 4 days a week vs 5) are constrained by e.g. people who are willing to work 5+ days a week 12 hours a day.

* To be clear, I know very well that most people don't even have such a choice in the first place.
