You would have money. The people who used to work the security positions would not have money, and it's an open question whether your consumption of many products (such as food) could keep up the consumption rates to justify the production to keep the market operating at its current flow levels. If they can't, the market would have to contract, which means if what you're guarding is a food store, you may also find yourself out of a job because we no longer need to guard the food nobody is buying. This is how Great Depressions occur.

And that's just looking at the numbers. Stepping away from the simulation and getting into what it represents, we realize we're looking at a situation where some people have the money to do whatever they want and many, many more starve. If the system is structured to make that happen, the system is flawed by several quite reasonable metrics.

Where do you get your money? I'm assuming from customers paying you. But customers will only pay you as long as they have money. If the trend toward this kind of automation keeps going, then the number of customers with money will keep shrinking and shrinking.
