From the ISO’s kick-off forum “Why You Should Join the Socialists & Change the World”.
"Starbucks baristas make about $9/hr. If they make 3 drinks for $5 each, they pay for their hour of their labor & supplies. At 5 drinks they pay for themselves & a coworker. At 10 the whole store for an hour. At peak hours they make 2-300 drinks & see none of the profits. Every drink after 3 is theft."
I think this is interesting and I get the point you are trying to make except you are forgetting one simple thing.
Not all of that “Profit” is actual profit. Businesses have to pay for more than just their employees. Building space, supplies, merchandise, bills, everything else that goes into making a business function.
I get that you were trying to make the point that employees are way underpaid, but I think you are forgetting about everything else that goes into making a business successful. At the end of the day, that profit is not as great as you think it is.
If you want to make a negative point about Starbucks, maybe you should look into how much it pays the people who grow the coffee beans. The claim that they are fair trade is actually a lie.
