Yes, and I know my phone is made by small children. I know that these situations exist.
But, everything is made in this way. If you try to go "nice" and buy shit that's made by some old people in eastern France, it'll cost you a pretty penny. I agree, those kids have it horrible, and it definitely should change. But that's only possible if the people who run those companies decide collectively to shut down their sweatshops. And we can whine, weep, and scream bloody murder, but they'll never change.
You want to change the world? Run the world first.
I sound like an asshole, I know.
But at least I'm an honest asshole.
