In Australia, there's a big ongoing investigation into price gouging from our supermarket duopoly. i.e. hiding under the cover of inflation in order to wrench more profit. Something less talked about is their ruthless surveillance of anyone who exists within the store. Machine learning assigns an ID to every customer, and in some stores, if it deigns that you have shoplifted, the exit gates literally do not open. Woolies and Coles are also investing in crime-prediction tech, the same kind of flawed, biased stuff used by the police. Staff wear body cameras. This is apparently to protect them against harassment from consumers (who are getting even angrier because the supermarkets are ripping them off). But it's also a potential vector of surveillance and control against the staff members themselves. https://theconversation.com/the-secret-sauce-of-coles-and-woolworths-profits-high-tech-surveillance-and-control-224076
