The problem is structural.
The workers create the value, absent the work, there is only raw resources with no value to the owners.

At each step, in order to stay in business, a company can pay no more than half of this increased value.
Ergo, the worker gets less than half what his work is actually worth.

Read chapter 9 of this book and debunk the math, please.

IF a company pays more than half to its workers it will go out of business.

This book covers the topic in depth.
It is written by a russian noble that abdicated his royalty in favor of treating the workers right, rather than exploit them.
