Inverting the pyramid
As the actual "producing stuff" gets more automated and therefore cheaper, companies will be able - maybe even required - to employ more layers of managers, supervisors and other clerical roles. We have seen this ever since the 1960s: as mass-production improved, the cost of manufacture dropped, the cost of transportation was reduced and goods got cheaper, into the bargain.
Yet, in order to have a market to sell those goods into, it is necessary to have a large number of employed, well-paid, individuals to actually buy the stuff: consumers. Without them, it doesn't matter how cheap, well-made or innovative something is.
Even 20+ years ago when I worked for a large multinational as a consultant, The overriding element of that company was the number of unproductive administrative staff they employed. I had calculated that from my hourly rate - of which, being an employee I saw very little, they were employing 6 other people, simply based on what they charged for me; at the sharp end - the guy who actually had billables.
And so it will be in the future. When all the productive, revenue earning, work is done by machines companies will still employ the same number of people. But instead of stamping out widgets, selling shiny products to the gullible or explaining to a client why a database table with 1200 VARCHAR columns won't access very fast (will update even slower), will be a nightmare to maintain and probably isn't even what they want - all those employees will while away their days in meetings discussing exactly which shade of brown their packaging boxes should be and whether the risk-assessment for moving the company logo 2mm to the left on the letterhead should be out-sourced or done in-house.
