Does the AI care how many people there are so long as the aggregate demand is the same? Who is to say that the people remaining on the AI company payroll don't all get super-rich and make up 20% then 40% then 80% then 99% of the market anyhow? Maybe they all want mega-yachts and rockets and personal airplanes and the like. If they have the money to pay for it why does the AI care? There's a substantial benefit to only having 100 or 1000 or 100,000 customers, they're much more predictable and easier to understand.
