The workers work 12 hours a day and their income is less than a dollar

Wow, this is horrible.

Why is it a comma?

That might sound impolite, but it´s serious question - What can WE do with it? How can I find out the condition of maker of every piece of clothes I buy? How can I prevent it?

I know this isn't the message portrayed but I read it as the materials to make the dress cost $0.60 not that she got paid $0.60 to make it.

$0.60 is money. It's not much, but it's better than nothing, without this employment, she may not be able too eat, so she'll stave and die. $0.60 may buy considerately more than it would do without a massively inflated economy. I realize that she's not paid fairly, but I doubt that the people who pack, ship, advertise and sell the dress are paid an equal proportion of the profit either. $0.60 is better than $0.

50 dollars? hook a bitch up,
