In real terms, workers on minimum wage in the US get paid less today than in 1950, while corporations have been posting record profits after record profits in the past decade. It's not how much the worker gets that's the problem, but how much their employers gets. Exxon Mobil's profit went from US$8 billion to US$45 billion between 1999-2008 and, despite no increase in minimum wages during 99 and 2007, they cut 26,000 jobs during the period.
The employer doesn't pay the worker to produce a product (e.g. you get paid X to produce Y number of items). The worker sells his work force for a determined period of time, during which the employer extracts the largest share of its profit through seizure of surplus-value. That will only be concretized at the sale of the product, but its not the product's face value that will affect the worker's salary, because they've already been paid (through the result of their own work) to do it.
If I'm paid to produce something that's gonna be sold for 40 dollars every 20 minutes, for six hours, six days a week, I could be paid $170.000/year and my employers still would keep the company profitable, just less profitable than its owner feel its right for their pockets.
If every person who liked it or shared it paid him £0.10 by Paypal or whatever, he could give the car away to someone who needs it and still have all his money back!
In fact, this pretty much sums up how most of will feel in a couple decades:
"Encumbered forever by desire and ambitionThere's a hunger still unsatisfied
Our weary eyes still stray to the horizon
Though down this road we've been so many times"
