Maybe we'll actually reach some future where all production and maintenance labor is fully automated and most participants in an economy won't be human and we can just ethically enslave them for the benefit of human owners, but we're nowhere near that point.
I'm living right now in a hotbed of construction, a rapid growth metro, and I'm in the middle of it. Three lots I can see from my bedroom window are being leveled and turned into townhouses. That work is being done by people. They certainly have machine work multipliers. Nobody is carrying lumber and stone by hand from quarries to job site. Nobody is leveling the earth with shovels and trowels. But the bobcats and trucks are still operated by humans. Pipe is laid by humans. Walls are erected by humans. If all those people tried to do my job instead and became coders, or worse, tried to become investors, I and all the investors would be left with nowhere to live because no one would be building houses. We'd have no water or electricity if no one was laying the pipes and lines.
At some point, we should realize this and attempt to have an economy that recognizes most people in the economy have to be doing basic labor for there to be an economy at all, and figure out a way to accomplish this without these people needing to live paycheck to paycheck with the looming threat of a medical emergency able to wipe them out permanently. We can't just tell them to all change their focus from doing work to building wealth, because if they actually all do that, there will no longer be any wealth.
