At the risk of being the person who says, "it's capitalism," (I know I know).... When making profit is the dominant intent of a company, a worker doing something faster doesn't lead to the worker doing less. It leads to the worker producing more in the same time. If doing more yields too much of the thing produced for the market to handle, the company either A. creates more need for the more produced (fabricate necessity), or B. creates a new need for a new thing, and a new thing for you to produce. There's no getting off the wheel for the worker in capitalism.
