We can, however, stop buying products made in such dangerous factories, and make it clear why we are doing so. Why should we demand that factories in this country adhere to certain safety standards, then buy cheap goods from factories in other countries that do not adhere to the same standards?
Yes they need safety regulations, but that really does need to come from the Chinese workers. We should help them make those demands if they want but we shouldn't force it on them. I.E. Opening a site where workers can Chinese workers can complain about their working conditions (ratings) which then propagates those ratings to the products. We would use the product reference as a guide.
But to force that upon them, in my mind, is wrong. It's hard to find the line between empowerment and external control. This is an issue many Americans had when donating to Haiti. They'd try to give an American fix and it didn't work because that's not what Haitians wanted or needed.
How do you know what factories are dangerous?
For the USA that meant better working environments, hours, safety, and pay. Before these things were in place we had insufficient labor laws here too. The portion that I'm missing is that, here in the states our industrial revolution paid well enough for parents to provide a better standard of living for their children. Those children were able to do the same, and we increased the middle class. If that is what is going on in China then we should NOT stop purchasing good from them.

However, I think the OP being concerned about this is great, but you can't force change onto another culture nor should you. We can attempt to empower them to make the change, and be aware so that we aren't supporting the a workforce that is being sucked into a cycle of poverty.
