Wolff is a wealth of information on this critical and pivotal topic. Everything seems to follow from how the surplus is organized.
Once you see this fact, the whole system is revealed. I spent years uncomfortable with how the employer/employee relationship worked. But once it was pointed out that it's based on exploitation, it all came right into my conscious. And that's the only way we can control it.
We can have revolutions, and all the rest, and still fail, if we don't turn this one thing around.
What's revealing is how Wolff points out the 150 year period of rising income, right up to the 70's. And once you know that tidbit, it becomes obvious what happened to our society.
We're so far down the road after the 70's, we just cannot afford to continue. And even when wages were rising we were being exploited, but could tolerate it due to the rising wages.
Also what he points out is how when wages failed to continue rising, the capitalist owners of our society decided not to pay us more, but to instead LOAN US MONEY. And the rest is history. Now we work more in order to consume the same amount.
If people understood this, we'd see a lot different topics being posted on this forum. But the problem is, through indoctrination, we have been taught to pretty much ignore this topic.
