Payment? How? 

In the bookkeeping text I'm studying it says: hours worked times rate of pay minus taxes deducted is net pay. In the specific example the employee was paid about the federal minimum wage. Looking at it from the employee's point of view it seemed nowhere near enough. Looking at it from the employer's point of view it seemed impossible, because it had to come from not only charging more for products than the company bought them for but also from people actually buying it and being able to buy it. I wonder what the book was leaving out. Then, I read this article and it didn't tell me either. Tell me, how does the free market add up? Why does it work? Is it a miracle? Is it some part of business I don't know about?
