No, that's not it.
I wish I had - but I do emphasize (sic) with them - they are being screwed by the owner class, as the owner's take advantage of the their usually inherited positions to plunder the worker class of their activity, ingenuity, and productivity. It is time to push back, to gain some equity in what we produce.
This might be it:
The value of a product equals the amount of labor that goes into making it. For example, if a factory buys some wood for $50 and then uses $100 worth of labor to turn it into a table, the fair price for the finished table is $150. Any excess that the factory charges - any profit - is thus a theft from both workers and consumers; and as this stolen value accumulates, the factory owner gets to exploit society on an ever larger scale. Or as Marx puts it in his own high style, "Capital is dead labour, that, vampire-like, only lives by sucking living labour, and lives the more, the more labour it sucks."
Dang spell checker, I'm getting dyslectic. (Never mind).
I believe that the factory owner does bring value to the product, as do executives and managers, of course - but in today's economy I believe that company executives and managers are taking a disproportionate share of the produced wealth. Even the owners of widely held public companies are being sacked by this group. They are out of control.
