Earlier quoted context omitted.
If efficiency has gone up why hasnt rent gone down? Since rent has been pushed up by political means why not wages? Also, why are we assuming that technology brought down wages when offshoring has skyrocketed. What makes you think it wasn't competition from the third world labor rather than robots? There is a political position embedded in the assumption that robots are responsible for the missing jobs.
I would guess this speaks more to political mismanagement than an intentional goal. No politician is going to get elected on a platform of higher rents and lower wages. Increased rents, at least, are usually caused more by good intentions gone bad than by intentional malice
Have you noticed how little the media focuses on the actual platforms of most politicians and focuses on the spectacle and drama of politics instead? That distraction serve a purpose (for the owners of said media).
Also, a platform of higher rents and lower wages will usually be called "lower taxes" and "freedom from onerous regulations". If you want to see more of this type of propaganda, look at https://www.aei.org/ for instance.
This type of thing falls apart when analyzed too closely, which is partly why the media will use it to drive soundbites but won't dive in too deep.
Politicians get elected on a platform of higher rents and lower wages because the donations they rely upon come from people who want it and the media coverage they rely upon come from people who want it.
