Thats false, small businesses like a 5-man refrigeration repair company would not try and screw over their workers. But unfortunently when it came to my dads business the workers screwed him over instead. Irony is though that they thought the gross pay was the actual profits his company obtained when thats just the pay before the deductions.
And his buisness was doing really well, he had practically every fast food restaurant in Alberta as a customer.
Your father owned the capital(the company, tools, etc) and employed the workers offering them a wage for their work.
Now it wouldn't be very smart for your father, as the business owner, to pay the workers wages that exactly matched the value of their labor would it? Where would his money come from? In order to get a profit to live off of and maintain capital, your father needs to pay his workers less than what their labor actually produces so he can make money off of their work. Follow?
This is how capitalism works! Workers are paid in the form of wages a value less than what their labor actually produces so the employer keeps the surplus value(the difference of what the labor was worth and what the laborers were paid) as profit. Workers get the raw end of the deal.
