That's not what they're saying the issue is though, the issue is how it's redistributed. In fact, what you're saying quite literally is the living example of anti-progress.

It could be fine in the current state if companies paid people fairly, but they don't, any progress or efficiency that could have been made was stifled by the company pocketing the ex-employees wage. Rather than supporting the current employee by giving them a raise or a team of members to work with, it's taken.

To put it this way: Bob and Janet are janitors who split their work equally. A new tool the company bought is able to cut their workload down by 15% each. Now Bob and Janet only have 35% of their work, instead of 50%.

A good workplace will support Bob and Janet in various ways, making them both more efficient by being able to accomplish more tasks.

A bad workplace will fire one of them, making the work load for one of them to 70%, without supplemental pay.

That 35% of value Janet brought is no longer going into the economy, it's going into the corporate profit.

It's very efficient. That's why corporations do it. Now one worker is extremely overworked and underpaid, but the job still gets done and the company makes more money? Sounds like a win.
