Just wait til they manage a more robust data extraction method. We see this already with appliances you can buy, through which you record what/when you are watching on TV, how many viewers, etc - and you get paychecks, presumably negligible ones.
Eventually: Pay people to get hooked up into some virtual-reality-electroencepholography focus-group/beta-tester simulation, run the Consumer Experience, record electrical and/or chemical activity in the brain, and then reverse-engineer the experience, based on feedback, to optimize consumer experience.
Simulations, if operationalized this way, could cut research and development down to a fraction of its cost, no? Fine-tuning a simulation ought to be orders of magnitude less expensive than reiterating supply and production chains, no? This could very well be the bottom-of-the-barrel occupation, at some point, for those who aren't literate enough in programming languages to avoid effectively becoming data slaves, infinite repositories of data, exploitation abstracted beyond labor.
Even scarier, this whole operation could be marketed as some cutting-edge new-age form of labor. No need to exert yourself, get a decent paycheck for just sitting through some techie-headset experiment. Might not even need to leave the house. There would be a virtually unlimited amount of data to collect, so there is your income security. A culture could form around it, with a sensibility of ripping the man off, getting paid to "do nothing", etc.
Hell, since brands will have already firmly colonized our identities, being a beta-tester for a favorite brand could be an additional point of pride, and this pride could also be exploited.
This would also be a job that only humans could do, because by the time data harvesting is automated (on both sides: harvester and harvestee), we're either in the dust or we've reached communist heaven.
edit: or we're in those matrix pods.
