That's not true - foreigners do have a say in that we can refuse to purchase products from companies that enable this behavior (which includes Apple, Google, Dell, HP, etc etc).
But we don't, because we'd rather have cheap stuff.
You're not changing anything.
Apple is a big, juicy and rich target and their Supplier Reports show great promise. It might not be fair on some absurd abstract level (I don’t think Apple is evil but I have no problem when Apple is attacked for the working conditions) but it seems like a strategy that is very likely to succeed.
Apple can force suppliers to make laptops out of aluminium. Why shouldn’t they be able to force them to better working conditions.
