In what way have we "eliminated them systematically"? Maybe I haven't paid close enough attention, but it feels like those activities have (unfortunately) disappeared largely naturally.

Take this question a step further and ask _why_ those activities disappeared. What are those people who would previously have been doing that, now doing instead? Usually, the answer is working. For the unions, decades of policy have systematically eliminated them, but for the other points, it's more of a "between the lines" thing.
