You make good points, but I have to disagree with #3. If a business cannot exist without a certain type of labor, then that labor is responsible for 100% of the business’s produced value. Yes, this might result in a $45 burger and fries, but we’ve been coasting on exploitation for decades and have been sheltered from the true cost of goods and services.
Plus, there are a plethora of jobs that are overdue for being replaced by robots, but haven’t yet because exploiting humans is cheaper. If someone who mops the floor gets a $35/hr wage, we might finally get a commercial-grade mopping robot that doesn’t get the damn mop head caught on every chair leg and fridge wheel.
