You have to look a level deeper. Life has always been productive, it’s the only way you maintain negative entropy and thus life itself. If you found a species that stopped being biologically productive, you would recognize that as a maladaptive deviation from the norm (and that species would quickly go extinct).
You should work hard to be productive for humanity, not owners, who themselves are also subject to their own biological drives and pressures that channel them just like these same drives channel others.
If you feel exploited, then be productive in ways that circumvent your exploitation. Working hard and being productive is far older and more fundamental that capitalism though, and for your own sake and humanity’s sake you should embrace it.
