Then you say:
//If we were paid based on our productivity
We are paid for our productivity in the grand scheme of things. To make this obvious, many things that would have taken hours/days for a worker to do 200 years ago may be done in seconds with today's tooling. So if you want to live like people did 200 years ago, you can do that with minimum work (in fact, in the west you have a much better life unemployed today than a worker would have 200 years ago). But the reality is, you want the improvements of safety, quality of life, etc that have occurred in that time too. Because you want your life to be "better."
