The products become cheaper because of competition with other products, automation is just part of what allows business to have a lower cost themselves.

Apple and tech in general are actually a good example of my point. Why is it that in several third world countries, lacking basic sanitation for a large part of the population, it's so common to see people in slums with last generation smartphones and big flat screen TVs?

What I meant about everyone getting richer is not that the money flows equally, but that when you need less money to buy goods and services you are, in a way, richer. Another example is Uber: I don't get a single dollar of what they make, but I have access now to a service that it wasn't accessible before (taxi cabs).
