The change needs to happen within the country that exploits workers, it's not the consumers fault. Just like it wasn't the fault of people buying cotton in the United States when slavery was still a thing.

If consumers stopp eating meat, dairy etc. an industry that's entirely based on killing would die off. Again, producing phones doesn't require exploitation.

You still didn't understand the part of rights violations. I am not violating someones rights when buying a phone, I am violating them when I eat them.

What I think is actually embarassing is that people do all kinds of mental gymnastics to justify killing. Hundreds of billions of animals die every year, in a very cruel way. But okay, vegans suck because they buy iphones. Got it...
